Transmission system, transmission method, transmitter, receiver, decoding method, and decoder

摘要

A transmission system capable of obtaining an effect of orthogonality among time block codes and an effect of path diversity on a distorted channel is provided. In the transmission system including: a transmitter device transmitting an information signal S[n] multiplied by a code, the code being a time block code constituted by a plurality of time series symbols, the transmitter device multiplying the information signal by a plurality of the time block codes, respectively, multiplexing multiplication results on a time axis and transmitting multiplexed signals; and a receiver device including a reception filter, if an impulse response matrix of a channel is a matrix H, a characteristic of the reception filter is set to be represented by a complex conjugate transpose matrix HH to the matrix H and each of the time block codes is set by an eigen code E_I[n] represented by an eigen vector of a matrix HHH representing a coupled system in which the channel is coupled to the reception filter.
