Takara

Takara Co. Ltd. was a Japanese toy company founded in 1955. In March 2006, the company merged with Tomy Co. Ltd. to form Takara Tomy. The Takara motto was 遊びは文化」. In 1967, Takara produced the first generation of the Licca-chan doll, 21 centimeters tall and had the last name of Kayama, inspired by the musician Yuzo Kayama and actress Yoshiko Kayama. In 1975, Takara produced the Microman Micro Change toys. In 1984, the toy line was rebranded by Hasbro as "Transformers", which made Takara waste no time joining in. Takara used it as the basis for the Micronauts toy line. Micronauts were sold internationally by the Mego Corporation. Other transforming toys made by Takara include Brave, Dennō Bōkenki Webdiver, Daigunder. Both Webdiver and Daigunder toys could interact with TV screens, which proved only but a fad in the early 2000s. Takara invented Battle Beasts, the E-kara karaoke microphone, B-Daman and Beyblade; these toys were distributed internationally by Hasbro. In 1978, Takara developed the Choro-Q, mini pullback cars.

Internationally, they have been sold as "Penny Racers". Takara published video games. In the 1990s, Takara published the Chibi Maruko-chan video games; the company ported some of the SNK Neo Geo based arcade games for 8 and 16-bit consoles. These included the Samurai Shodown series, they were sold for use with the Sega Genesis, the Super Nintendo Entertainment System, the Game Boy, or the Famicom. In 2003, Takara contributed to the production of the game, Seek-and-Destroy. Takara published the 3D computer graphics fighting game series Battle Arena Toshinden, developed by Tamsoft. Small games developers such as Tamsoft, BHE, E-game and KID corp, were sometimes omitted from the credits on a game's Takara packaging or title screens; that year, Takara purchased a controlling stake in the publicly traded software publisher Atlus. Some Takara properties were published by Atlus. In 2006, after the merger with Tomy, the controlling stake in Atlus was sold to Index Holdings, Takara Tomy's major shareholder.

Takara-branded product licenses such as Licca-chan, Jinsei Game, The Game of Life and Choro-Q were returned to Takara Tomy's consumer software division. The merged company produced the Zoids and the Naruto series. Takara has manufactured several unusual gadgets marketed as "life entertainment products". An example is BowLingual; the BowLingual was named as one of the best inventions of 2002 by Time magazine. See Yumemi Kobo. In 2005, Takara produced a colorful, multi-function miniature robotic turtle, it was named Time magazine's best invention in a robot category. In the 1980s, the company was criticized for using a mascot, a golliwog-like character; the mascot was named "Dakko-Chan". Takara replaced the mascot with "21st Century Colorful Dakko-Chan", which had enough features to connote the original mascot but divested the traits which brought criticism. For example, the new mascot was not always coloured black. On 13 May 2005, Tomy announced their merger, it became effective on 1 March 2006. In English, the official name of the merged company is "TOMY Co. Ltd." while in Japan the legal company name is "K. K. Takara-Tomy".

TYO: 7867. In deciding upon the merged company's new name, "Takara" was used for its international brand recognition and "Tomy" was used because it was a trusted brand of infant and preschool products in Japan. While Japanese commercial law allows wide latitude in translating Japanese corporate names into official English names, the merged company took the unusual step of adopting "TOMY Company, Ltd." as its official English, while using "K. K. Takara-Tomy" TYO: 7867 in Japan. Both Takara and Tomy held licenses to distribute Hasbro products in Japan; the products include "The Game of Life", Blythe dolls, Magic: The Gathering, Duel Masters trading card games by Takara and Monopoly, Super Soaker and Play-Doh by Tomy

Channel state information

In wireless communications, channel state information refers to known channel properties of a communication link. This information describes how a signal propagates from the transmitter to the receiver and represents the combined effect of, for example, scattering and power decay with distance; the method is called Channel estimation. The CSI makes it possible to adapt transmissions to current channel conditions, crucial for achieving reliable communication with high data rates in multiantenna systems. CSI needs to be estimated at the receiver and quantized and feedback to the transmitter. Therefore, the transmitter and receiver can have different CSI; the CSI at the transmitter and the CSI at the receiver are sometimes referred to as CSIT and CSIR, respectively. There are two levels of CSI, namely instantaneous CSI and statistical CSI. Instantaneous CSI means that the current channel conditions are known, which can be viewed as knowing the impulse response of a digital filter; this gives an opportunity to adapt the transmitted signal to the impulse response and thereby optimize the received signal for spatial multiplexing or to achieve low bit error rates.

Statistical CSI means. This description can include, for example, the type of fading distribution, the average channel gain, the line-of-sight component, the spatial correlation; as with instantaneous CSI, this information can be used for transmission optimization. The CSI acquisition is limited by how fast the channel conditions are changing. In fast fading systems where channel conditions vary under the transmission of a single information symbol, only statistical CSI is reasonable. On the other hand, in slow fading systems instantaneous CSI can be estimated with reasonable accuracy and used for transmission adaptation for some time before being outdated. In practical systems, the available CSI lies in between these two levels. In a narrowband flat-fading channel with multiple transmit and receive antennas, the system is modeled as y = H x + n where y and x are the receive and transmit vectors and H and n are the channel matrix and the noise vector, respectively; the noise is modeled as circular symmetric complex normal with n ∼ C N where the mean value is zero and the noise covariance matrix S is known.

Ideally, the channel matrix H is known perfectly. Due to channel estimation errors, the channel information can be represented as vec ∼ C N where H estimate is the channel estimate and R error is the estimation error covariance matrix; the vectorization vec was used to achieve the column stacking of H, as multivariate random variables are defined as vectors. In this case, the statistics of H are known. In a Rayleigh fading channel, this corresponds to knowing that vec ∼ C N for some known channel covariance matrix R. Since the channel conditions vary, instantaneous CSI needs to be estimated on a short-term basis. A popular approach is so-called training sequence, where a known signal is transmitted and the channel matrix H is estimated using the combined knowledge of the transmitted and received signal. Let the training sequence be denoted p 1, …, p N, where the vector p i is transmitted over the channel as y i = H p i + n i. By combining the received training signals y i for i = 1, …
