ABSTRACT:
At transmission, the data to be transmitted is divided into N data blocks, these N blocks are processed in parallel in N M-ary orthogonal keying (MOK) modulation channels, each modulation using a group of spread codes, each channel emitting a signal. All of these signals are transmitted in series. At reception, the signal received is processed in N M-ary orthogonal keying (MOK) demodulation channels, and the blocks obtained are grouped together in series.
