Abstract:
1. A code division multiplex (CDM) communication system comprising a transmitting apparatus and a receiving apparatus, wherein: the transmitting apparatus includes a plurality of frame generators for encoding and framing respective data signals and outputting resulting frames, and a frame combiner for combining the frames output from the plurality of frame generators to generate a multiplexed frame including a preamble signal followed by a preamble signal end bit pattern followed by a CDM signal followed by a CDM signal end bit pattern in respective time slots and outputting the multiplexed frame; and the receiving apparatus includes a clock signal extractor for receiving the multiplexed frame, extracting a clock signal from the preamble signal therein, and outputting the extracted clock signal during at least the time slot of the CDM signal, and a CDM signal processor for receiving the multiplexed frame and the extracted clock signal and decoding the CDM signal in synchronization with the extracted clock signal to obtain a received data signal.
