…fading over its whole bandwidth. In direct-sequence systems, the signal can be detected by using a rake receiver. Multiple access capability, known as code-division multiple access (CDMA) or code-division multiplexing (CDM). Multiple users can transmit simultaneously in the same frequency band as long as they use different spreading…
