Filed: 1993-09-20
Abstract: PURPOSE:To improve the quality of an outgoing radio channel by applying pre- distortion to a signal of an outgoing line depending on the characteristic of a transmission line of an incoming radio channel. CONSTITUTION:A mapping section 105 allocates generated data to a slot corresponding to each terminal equipment of a transmission destination at transmission, the data are subjected to time division multiplexing, a pre-distortion(PD) section 106 applies pre-distortion to the data to make equalization corresponding to the characteristic of the transmission line and a modulation section 107 modulates the carrier with the data and the result is transmitted. An equalization section 103 uses a coefficient update algorithm section 108 to update an equalization coefficient. The section 108 uses a unique word of a received burst, a training signal from a training signal generating section 109 (the same signal series as UW) and an output signal equalized by the equalization section 103 to calculate an equipment coefficient. The coefficient is used not only for the equalization section 103 but also for the updating of the coefficient of the PD section 106. Since an outgoing radio channel is equalized without provision of an equalizer to a radio terminal equipment and without provision of a transmission characteristic estimate device, the quality of the outgoing radio channel is improved.
