Process optimization combination signal reception at radio receivers space diversity based on the pulse frequency error correction without return channel (FEC) generated by the demodulator.

摘要

Combination method of radio signals received by a diversity technique space, which can run through a programmable control unit (ELAB) which performs a first iterative optimization procedure of the quality of the combined signal (WESt) controlling the variation in the phase shift (o) introduced by a phase shifter (SFAS) placed on one of the two branches of the combiner (ATT-M, ATT-D, SFAS, SOM, IF-AGC, DISP and FLAB) of said received signals, which controls the amplitude of said signals (Vrxm and Vrxd), and evaluating the effects of said variations on the combined signal (Vcomb) through distortion measurements power (Vagc) and amplitude (Vdisp) in the band of the modulated signal (Vout), which can be selected as said first procedure one of the known methods.
