    • PROBLEM TO BE SOLVED: To provide a radio receiver that can be reduced in performance degradation of signals and for which a soft decision value can be calculated.SOLUTION: A radio receiver receives a transmission signal in which a bit sequence is subjected to bit conversion processing, scramble processing and M-phase PSK (Phase Shift Keying) modulation processing (M represents a positive integer), and contains a phase rotator and a demodulator. The phase rotator multiplies a first symbol obtained from a reception signal by a phase rotation amount of a signal determined by the scramble sequence used in the scramble processing, thereby obtaining a second symbol. The demodulator refers to a data rate and a signal point of a replica signal of N-phase PSK (N represents an integer from 1 to M) created on the basis of the bit conversion processing to demodulate the second symbol, and calculates the likelihood obtained through the demodulation as a soft decision value.
    • 要解决的问题:提供可以降低信号的性能劣化并且可以计算软判决值的无线电接收机。 解决方案:无线电接收机接收其中比特序列进行比特转换处理,加扰处理和M相PSK(相移键控)调制处理(M表示正整数)的发送信号,并且包含相位 旋转器和解调器。 相位旋转器将从接收信号获得的第一符号乘以由在加扰处理中使用的加扰序列确定的信号的相位旋转量,从而获得第二符号。 解调器是指基于比特转换处理产生的解调第二符号的N相PSK(N表示从1到M的整数)的复制信号的数据速率和信号点,并计算得到的似然率 通过解调作为软判决值。 版权所有(C)2013,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a transmitter, etc. for spectrum aggregation which synthesizes plural transmission signals having plural frequency bandwidths in a transmitter to generate a plurality of final transmission signals and then transmits those final transmission signals simultaneously for spread and multiplexed transmission, thereby making it possible to improve frequency diversity gain and, hence, to improve transmission characteristics.SOLUTION: Transmission symbols of plural carriers whose frequency bandwidths are apart from each other are subjected, as precoding transmission symbols, to rotation orthogonal coding, thereby generating coded transmission symbols. The plural coded transmission symbols respectively corresponding to plural carriers are respectively transmitted, as plural transmission signals, from plural transmission antennas toward a receiver having plural receiving antennas which respectively receive those transmitted signals, in which way spectrum aggregation is carried out.
    • 要解决的问题:为了提供频谱聚合的发射机等,其在发射机中合成具有多个频率带宽的多个发射信号,以产生多个最终传输信号,然后同时发射那些最终传输信号进行扩展和复用 从而可以提高频率分集增益,从而提高传输特性。 解决方案:将频带宽度彼此分开的多个载波的传输符号作为预编码传输符号进行旋转正交编码,从而生成编码的传输符号。 分别对应于多个载波的多个编码发送符号分别作为多个发送信号从多个发送天线向具有分别接收那些发送信号的多个接收天线的接收机发送,以这种方式进行频谱聚合。 版权所有(C)2012,JPO&INPIT
