摘要： A receiver for transmission and parallel interference has multiple access interference suppression stages having K channels, each comprising a correlation device corresponding to a particular pseudorandom sequence and interference generation and suppression device. Each stage delivers to the following stage signals at least partly freed from multiple access interferences. A decision stage receives the signals from the channels of the preceding suppression stage. Each decision stage has a correlation device corresponding to one of the pseudorandom sequences and decision device to deliver data. Devices for producing synchronization signals can control the interference suppression and the decision device. The devices producing the synchronization signals have components placed in the channels of the final stage. Further, the synchronization signals produced by these devices control the decision device of the channels of the final stage and the interference estimation device of the at least one interference suppression stages following appropriate time shifts.

摘要： 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.
摘要翻译：在发送时，要发送的数据被划分为N个数据块，这些N个块在N个M进制正交密钥（MOK）调制信道中并行处理，每个调制使用一组扩展码，每个信道发射一个信号。这些信号都是串联传输的。在接收时，接收的信号在N个M进制正交密钥（MOK）解调信道中被处理，所获得的块被串联分组。

摘要： A method and an apparatus for transmitting data using multi-MOK modulation/demodulation transmission process corresponding to transmitter and receiver are disclosed. At transmission, the data to be transmitted is divided into N data blocks. The 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 these signals (S) are transmitted in series. At reception, the signal received (R) is processed in N MOK demodulation channels and the blocks obtained are grouped together in series.
