摘要： PROBLEM TO BE SOLVED: To provide a modulation/demodulation system capable of minimizing bit error rate in six-phase phase modulation system. SOLUTION: Six-valued signals outputted while being subjected to phase modulation at a modulator 1 are received by a destination demodulator 2 and subjected to phase demodulation thus obtaining a binary signal before being modulated by the modulator 1. The modulator 1 assigns six-valued signals (b i , t i ), i.e. (0, 0), (0, 1), (0, 2), (1, 2), (1, 1) and (1, 0), respectively, to first through six phases. In the conversion processing from a six-valued signal into a binary signal by the demodulator 2, six-valued signals being transmitted are stored and every m six-valued signals are converted sequentially into b binary signals and outputted. In the processing of the demodulator 2, first through sixth phases are assigned as the six-valued signals (b i , t i ), respectively, to (0, 0), (0, 1), (0, 2), (1, 2), (1, 1) and (1, 0).

摘要： PROBLEM TO BE SOLVED: To provide a modulation and demodulation system capable of minimizing the bit error rate in the six-phase phase modulation method. SOLUTION: A modulator 1 in its processing assigns (0, 0), (0, 1), (0, 2), (1, 2), (1, 1) and (1, 0) which are senary signals (Bi, Ti) to first to sixth phases respectively, wherein i=1 is a first symbol, i=2 is a second symbol, Bi is a binary signal, and Ti is a ternary signal. A demodulator 2 performs a conversion process from the senary signals to the binary signals, for instance, by storing the transmitted senary signals and sequentially converting every 2 pieces of them to 5 pieces of binary signals so as to output them. The process of the demodulator 2 assigns the first to sixth phases as the senary signals (Bi, Ti) to (0, 0), (0, 1), (0, 2), (1, 2), (1, 1) and (1, 0) respectively. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To a modulating method and device for realizing transmission with transmitting power smaller than that of 2
(n + 1) phase modulation by using, for example, bandwidth between A and A/2 to be able to obtain an equivalent coding error rate in the case of requiring A bandwidth in 2
n phase modulation and half of A bandwidth in 2
(n + 1) phase modulation.
SOLUTION: In this modulating method for making a binary signal of length b for the number N of phases (integer other than power of 2) of phase modulation correspond to an N-ary phase signal of length n and transmitting the binary signal of length b, the average error rate of each bit of the binary signal of length b is associated with all errors of distance 1 of the N-ary phase signal of length n so as to minimize the average error rate.
