Radio communication system, transmitter and propagation path quality presumption device, propagation path quality presumption method and program

摘要

Low, quantize noise the decrease possible communication system and the like is proposed even with when resolution ADC is used. Transmission signal formation department 10 of transmitter 3 forms the transmission signal by doing fixed envelope irregularity processing on the basis of phase. Receiver 5 quantizes the reception signal making use of resolution ADC39 low. With resolution ADC, quantize noise appears low remarkably. But, as for quantize noise, low being resolution ADC from the fact that it occurs remarkably in amplitude, by doing the fixed envelope irregularity processing which uses phase, you avoid quantize noise, high accuracy it becomes possible to actualize communication. Furthermore, compared to doing propagation path presumption in high accuracy it becomes possible by calculating repetitively high accuracy radio communication from the fact that it is actualization possible, in propagation path quality presumption section 33.
