摘要： A transmission apparatus and method for a communication system based on Orthogonal Frequency Division Multiplexing-Code Division Multiplexing (OFDM-CDM). A frequency spreader multiplies symbols to be transmitted by a frequency spreading factor and outputs frequency spread symbols whose number corresponds to the frequency spreading factor. Buffers whose number corresponds to the frequency spreading factor temporarily store the frequency spread symbols in a unit of a predefined number of symbols. A time spreader multiplies parallel frequency spread symbols from the buffers by a time spreading factor and outputs frequency-time spread symbols. An Inverse Fast Fourier Transform (IFFT) processor performs IFFT on the frequency-time spread symbols, and outputs an OFDM symbol. A Guard Interval (GI) inserter inserts a GI into a signal output from the IFFT processor and transmits the signal. The system can obtain complete diversity gain and residual gain due to the effect of a time-varying channel in any channel environment.
