<p>A time division multiplexing method and system, it uses multiple symbols to parallelly transmit data serials in time domain. The method includes the steps of: the transmitter generates the transmitting signal with multiple symbols overlapped in the time domain; the receiver detects the received signal in the time domain based on the data serial, according to the one-to-one relationship between the transmitting signal and the temporary waveform of the transmitting signal. Moreover, the present invention provides a time division multiplexing system according to the time division multiplexing method. The present invention also utilizes the overlap to generate a restrict relationship between codes, therefore it effectively improves the frequency spectrum efficiency. Meanwhile, in the random time-varying channel, it can improve the transmission reliability of the system if properly arranged; under the condition of the same signal-to-interference ratio threshold, the frequency spectrum efficiency is much higher than other techniques, such as the high dimensional modulation; and under the condition of the same frequency spectrum efficiency, the overall level of the system and the required signal-to-interference ratio threshold is much lower than other techniques, such as the high dimensional modulation.</p> |
