<p>A procedure and device for variable reception in a communication system are presented. The receiver (100, 101) featuring two branches is equipped with a stored replica of the anticipated reference information (104), so that the correlation to the received time dispersed signal produces an estimate of the channel impulse response upon transmission, as seen by each of the branches (100, 101) thus among others determining the phase error rate between local oscillators (208, 209) within each branch and the time dispersed signals. Adapted filters (214, 215) are provided which then coherently align time dispersed signals from each of the branches (100, 101) with the local oscillator (208, 209) of the branch, being part of the signal alignment. A variable processor (105) executes a bit by bit selection on the realigned signals, combining with the largest ratio of the realigned signals or combining with realigned signals of equal amplification, followed by the estimation of the sequence, which uses similarly selected or combined parameters by channel distortion equalisation to conclude the equalisation process for a new signal.</p> |
