A method for receiving multicomponent signal in radio contact with the N transmission channels amp; M receive channels (optional) AND DEVICE FOR ITS IMPLEMENTATION (optional)

摘要

FIELD: information technologies.;SUBSTANCE: instead of traditional quantisation and formation of estimates of figures of modulation from the gained quantised estimates, carry out the multialternative (multiple) quantisation and formation of candidate vectors set. A candidate vector is a plurality of figures of the modulation which are quantised (rigid) estimates N of transmitted information signals. The set of candidate vectors is made of several most probable quantised estimates of each of transmitted figures of modulation. Candidate vectors are shaped in space of the modified signals, and then will be conversed to space of initial signals. The gained set of candidate vectors is used for search of the solution minimising decision function of the peak credibility, or for formation of metrics for the soft decoding.;EFFECT: increase of noise stability of a multicomponent signal reception, in system of a radio communication without coding, and in system of a radio communication with coding.;21 cl, 9 dwg
