Mobile communication system capable of transmitting and receiving a radio signal obtained by TDMA and CDMA without interference

摘要

In a communication system from a mobile station to a base station, a transmitter of the mobile station subjects a sequence of transmission signals to both of time division multiple access (TDMA) and code division multiple access (CDMA) to produce a radio output signal located in a time slot of a frame. The radio output signal obtained by the TDMA and CDMA is filtered or inversely spread to remove interference and noise from the radio output signal by the use of an adaptive filter which has taps controlled by an adaptive controller.
