Abstract(in English) | We make an estimation of a maximizer of posterior marginals (MPM) as for a multi-valued information sequence by a code-division multiple access (CDMA) demodulator using a multi-valued spreading code sequence within a framework of a Bayesian inference. We calculate an estimation error of the CDMA demodulator and an information capacity of the CDMA channel by using a replica method. We clarify that the multi-valued information sequence and the multi-valued spreading code sequence are useful as for improvement of information transmission by comparing performance for several multi-values. |
