摘要： A diversity system in a mobile radio communication system provided with a plurality of antenna systems operating over a multipath medium in at least one of the sending path and the receiving path. At the sending path, a carrier wave frequency- or phase-modulated by a digital baseband signal is transmitted from a transmitting antenna. A plurality of receiving antenna systems are switched at a constant frequency higher than the signaling rate of the digital baseband signal but less than the frequency shift width of the frequency modulated wave or less than a product of the maximum phase shift of the phase modulated wave and the signaling rate, so that average-power dispersion in a signal element of the digital baseband signal received at the receiving antenna systems is effectively compressed. Alternatively, the plurality of antennas may be transmitting antennas, and switched at the same rate to achieve compression of average power dispersion in the baseband signal elements.

摘要： A data transmission method, data transmission system, and a transmitter and receiver are provided which can implement higher quality variable rate transmission by making a more positive rate decision. In a variable rate transmission method transmitting fixed time length frames, each including variable length transmitted data, a transmitting side transmits user data plus an error detecting code, and a receiving side, assuming the entire transmittable final bit positions of the frame data, carries out Viterbi decoding of the frame data to the final bit positions. If, at an assumed final bit position, the difference between the maximum value of likelihoods of a plurality of decoded data sequence candidates and the likelihood of the decoded data sequence obtained by terminating the decoding process is within a predetermined range, and a calculated error detecting code agrees with a received error detecting code, a decision is made that the assumed final bit position is the final bit position of the transmitted frame data, and the transmitted data is recovered.

摘要： A transmitter receiver implementing both frequency division duplex and time division duplex in one device in a CDMA mobile communication system. In the FDD mode, data in an interleave memory in an interleaver is read at a predetermined read rate V.sub.R =V.sub.N, where V.sub.N is a normal rate. In the TDD mode, a transmitting carrier frequency is set identical to a receiving carrier frequency, and the read rate V.sub.R of the interleave memory and the write rate V.sub.W of the deinterleave memory are set at V.sub.R =V.sub.W >2V.sub.N. The transfer rate V.sub.T from column to column of the memories are set identical in the FDD mode and the TDD mode. This makes it possible to create a vacant duration while transferring from column to column, and to perform reception or transmission during the vacant duration. The remaining operation of the TDD mode is the same as the operation of the FDD mode.

摘要： Disclosed is a wireless transmitter that can prevent deterioration of the error rate characteristic without reducing the data rate during mobile communications also utilizing THP for FDE. In the device, an equivalent channel matrix computation unit (118) computes weights to be used for FDE of a transmission block and an equivalent channel matrix indicating equivalent channels that are generated from channel impulse responses, and a decomposition unit (119) obtains a lower triangular matrix (L), that consists of a diagonal element that includes a high channel quality at the front of the transmitting block and a low channel quality at the rear, so as to indicate the channel quality of the transmission block, and an element indicating interference with the transmission block, and a unitary matrix (Q) by means of LQ decomposition of the equivalent channel matrix. A computation unit (120) uses the lower triangular matrix (L) and the average channel quality to compute a matrix (B) that minimizes the mean square error of all symbols between the transmission block before precoding and a block received by a wireless receiver. A preceding unit (103) performs THP of the transmission block using the matrix (B).

摘要： A digital modulation and demodulation scheme for radio communications which is capable of reducing errors due to fading while maintaining the characteristic of the M-ary modulation and demodulation scheme that it is robust against interferences. At the transmitting side, transmission data are divided in advance into blocks of LN bits length each and each block is divided into N sets of L bits data sequences. Then, orthogonal codes of M bits length each corresponding to L bits codes given by the L bits data sequences are generated, and N sets of orthogonal codes for each block are multiplexed into a multiplexed signal, such that M bits constituting each orthogonal code are dispersed in time in the multiplexed signal. A digital modulation is then applied to a carrier using the multiplexed signal.
