Time division multiplexing communication system with parallel structure and method for the same

A receiving apparatus of a Time Division Multiplexing communication system with a parallel structure, the receiving apparatus comprising:

• a receiving antenna to receive second serial signals from a transmission apparatus;
• a Time Division Demultiplexer (TDDM) to perform time division demultiplexing of the received second serial signals in a demultiplexing ratio corresponding to a multiplexing ratio of the transmission apparatus to thereby output the demultiplexed serial signals as a plurality of parallel signals;
• a plurality of demodulators to respectively demodulate the outputted parallel signals;
• and
• a Time Division Multiplexer (TDM) to perform time division multiplexing of each of the demodulated parallel signals to thereby restore the multiplexed parallel signals as a first serial signal.

A transmission method of a time division multiplexing communication system with a parallel structure, the transmission method comprising:

• performing time division demultiplexing of inputted first serial signals to thereby output the demultiplexed serial signals as a plurality of parallel signals;
• modulating each of the outputted parallel signals;
• adjusting a multiplexing ratio according to a channel state and a frequency bandwidth, and performing time division multiplexing of each of the plurality of the demodulated parallel signals to thereby output the multiplexed parallel signals as second serial signals;
• and
• transmitting the outputted second serial signals.
