    摘要： An automatic equalizer has a sampling-clock producing arrangement which is for, before selecting a sample timing, producing a sampling clock at the rate of L times of that after selecting, and after selecting the sample timing, producing a tap-coefficient selection signal according to the sample timing, and a sampling clock at the rate of 1/L times of that before selecting, according to the sample timing. In the sampling-clock producing arrangement, demodulation components are obtained in absolute values of impulse-response signals with respect to L sample timings, respectively. A selecting arrangement selects the sample timing by the use of the demodulation components. The impulse-response signals are produced in response to a sampled received-signal obtained by sampling a received signal with the sampling clock.

    摘要： An automatic equalizer comprises a transmission symbol sequence generation circuit 101, a parallel received signal estimation circuit 102, subtracters 103-1 through 103-6, absolute value squaring arithmetic circuits 104-1 through 104-6, adders 105-1 through 105-4, and a discriminator 106. Maximum likelihood estimation can be performed with simple operations by means of using added error signals given by adding square error signals obtained from estimated error signals for an N number of delayed received signals delayed by a time instant corresponding to 0 through (N−1) symbols, to select the transmission symbol sequence having the smallest error.

    摘要： Provided is a technique capable of reporting resource block allocation information with no waste when an allocated resource block is reported, because in the current LTE downlink, the waste of the amount of resource allocation information increases in some cases since a restriction is imposed such that 37-bit fixed scheduling information is transmitted. A resource block group consisting of at least one or more resource blocks continuous on the frequency axis is allocated to a terminal, and the number of controlling signals for reporting allocation information indicating the allocated resource blocks is determined.

    摘要： Provided is a wireless communication technique capable of supporting communication using a single component carrier, and communication using a plurality of component carriers. The communication using the plurality of carriers comprises a processing means for performing the signal processing in accordance with each of the carriers with respect to the common signal sequence used by the plurality of carriers. The present invention makes it possible to cope with the communication employing a single component carrier and the wireless communication employing a plurality of the component carriers. Further, PAPR of the reference signals can be made small because there is no possibility that the identical CAZAC sequence is used among the component carriers when a plurality of the component carriers are employed.
