摘要： The invention relates to a multiplexing method and a transceiver used in a TDMA radio system. The transceiver sets up a connection to another transceiver by transmitting modulated signals in time slots. The transceiver comprises coding means for channel-coding a signal that consists of bits and that is formed into a communication signal, and interleaving means for interleaving the bits of the channel-coded Signal into blocks of a predetermined size. The transceiver also comprises multiplexing means that receive blocks from the interleaving means and that multiplex the interleaved blocks of at least two channel-coded signals together. The transceiver further comprises modulation means for modulating the blocks multiplexed by the multiplexing means with at least four-level modulation before the modulated signal blocks are transmitted as a communication signal in a time slot, so that the transmission speed of the communication signal and the number of the connections to be established can be increased.
