ABSTRACT:
In a transmission method for simultaneous synchronous or asynchronous transmission of K data sequences consisting of data symbols, before transmission a specific signal form allocated to the data sequences is modulated on each of the data symbols of the K data sequences transmitted via a channel or K generally distinguishable channels, in order to generate the K transmission signals, which are all distorted by the one channel, or one of the K channels. In the receiver, continuous-valued provisional estimated values are calculated for some or all of the data symbols of the K input sequences according to a linear method, and a confidence level for the estimated values is calculated.
