摘要: A code division multiple access transmitter and receiver that makes it possible to reduce its size by designating a spreading carrier frequency in baseband. It includes primary modulator for performing modulation transmission information, thereby producing modulated I signal Q signal, generator generating with higher than rate of the secondary spread-modulating using code, outputting spread I-channel data Q-channel data, offset circuit offsetting center designated frequency, transmitting converting into transmitted signal.
