Abstract: Provided are an apparatus and a method for tail biting convolutional encoding. The apparatus includes a plurality of shift registers and at least one operator. The plurality of shift registers sequentially performs a shift operation on input bit-stream. The operator outputs an encoded bit-stream by performing convolutional encoding on an output of the shift register using a generator polynomial corresponding to a predetermined code rate. A transmission encoded bit-stream is created by replacing encoded data for a certain initial bit-stream of the encoded bit-stream with a bit-stream obtained by subsequently performing convolutional encoding on the initial bit-stream.

Abstract: A multi-input multi-output orthogonal frequency division multiplexing (MIMO-OFDM) transceiving system is provided, in which an MIMO-OFDM receiver feeds back ordering information, such as the order of power intensities of reception signals of a plurality of reception antennas, to an MIMO-OFDM transmitter. The MIMO-OFDM transmitter arranges subcarriers, to which data symbols have been allocated, so that the subcarriers respectively correspond to a plurality of transmission antennas, according to the fed-back information. Thus, a specific substream can be transmitted via a transmission antenna having the greatest channel gain. Consequently, the probability of properly recovering the specific substream is greatly increased.
