摘要： Disclosed is a space-time coding apparatus and method to flexibly adjust diversity/multiplexing orders in a multiple-antenna system. The transmitting apparatus for the multiple-antenna system includes a space-time code controller, an encoder, a demultiplexer, and a space-time encoder. The space-time code controller generates space-time codes by determining bases according to a multiplexing order required by a receiver. The encoder modulates and encodes data destined for the receiver in accordance with a predetermined modulation level. The demultiplexer demultiplexes data received from the encoder in order to transmit the data through at least one antenna. The space-time encoder space-time-codes the demultiplexed data using the space-time codes.

摘要： A method is provided for recognizing the frequency bandwidth of a base station in a mobile communication system with frequency bandwidth scalability where the transmission frequency bands of base stations and mobile stations having different frequency bandwidths are overlaid with one another. The base stations transmit to a mobile station first information, including information about their frequency bandwidths at the same frequency position over a minimum frequency bandwidth with the same center frequency. The mobile station recognizes the presence of the base stations by comparing the first information from the base stations and detects the frequency bandwidth information in the first information.
