摘要： A method for receiving modulation signals includes receiving a plurality of multiplexed modulation signals each transmitted from multiple antennas of a communication partner, wherein each modulation signal includes a pilot symbol sequence consisting of plural pilot symbols used for demodulation. Each of the pilot symbol sequences is inserted at the same temporal points in the each modulation signal. The pilot symbol sequences are orthogonal to each other with zero cross correlation among the plurality of modulation signals, each pilot symbol having a non-zero amplitude, the quantity of the plural pilot symbols in each sequence being greater than the quantity of the plurality of transmitted modulation signals. The method further includes estimating a transmission path distortion of the each modulation signal based on the plurality of received multiplexed modulation signals; and demodulating the each modulation signal including the plurality of received multiplexed modulation signals using the transmission path distortion.

摘要： Modulated signal A is transmitted from a first antenna, and modulated signal B is transmitted from a second antenna. As modulated signal B, modulated symbols S2(i) and S2(i+1) obtained from different data are transmitted at time i and time i+1 respectively. In contrast, as modulated signal A, modulated symbols S1(i) and S1(i)′ obtained by changing the signal point arrangement of the same data are transmitted at time i and time i+1 respectively. As a result the reception quality can be changed intentionally at time i and time i+1, and therefore using the demodulation result of modulated signal A of a time when the reception quality is good enables both modulated signals A and B to be demodulated with good error rate performances.

摘要： It is possible to demodulate a plurality of modulated signals transmitted from a plurality of antennas by using a comparatively small-size circuit with a preferable error ratio characteristic. Partial bit judgment units (509, 512) demodulates partial bits of the 64QAM-modulated signal by modifying which of the bits in the 6-bit strings constituting a symbol is to be demodulated depending on in which region of the IQ plane the reception signal point exists. This improves the partial bit error characteristic judged by the partial bit judgment units (509, 512), which in turn improves reliability of the reduced candidate signal point for use by a likelihood detection unit (518). As a result, it is possible to improve the error ratio characteristic of the final reception digital signals (322, 323).
