摘要：
In a CDMA cellular communication system, a forward CDMA channel is used to transmit information from a cell base to the mobile station. Conversely, a reverse CDMA channel is used to transmit information from the mobile station to the cell base station. The transmit portion of the mobile transceiver includes a microphone (12), a codec (16), a vocoder (14), a mask circuit (32), a convolutional encoder (22), a block interleaver (24), a 64-ary orthogonal modulator, an in-phase PN generator (38), a quadrature PN generator (40), filtering circuits (42, 44, 50, 52), a quadrature modulator (54) and a transmitter (56).
