Abstract:
1. A transmission apparatus of a Time Division Multiplexing communication system with a parallel structure, the transmission apparatus comprising: a Time Division Demultiplexer (TDDM) to perform time division demultiplexing of inputted first serial signals to thereby output the demultiplexed serial signals as a plurality of parallel signals; a plurality of modulators to respectively modulate the outputted parallel signals; a Time Division Multiplexer (TDM) to adjust a multiplexing ratio according to at least two or more different channel-related information, and to perform time division multiplexing of each of the modulated parallel signals in the adjusted multiplexing ratio to thereby output the multiplexed parallel signals as second serial signals, and wherein the respective second serial signals from the at least two or more different channel-related information are different; and a transmission antenna to transmit the outputted second serial signals, wherein the TDM compares a time diversity gain with a maximum time diversity gain when the time diversity gain is requested from a receiving apparatus, determines a number of the parallel signals to correspond to the maximum time diversity gain based on the compared result, and performs time division multiplexing of the determined number of parallel signals.
