Abstract

We have developed an adaptive receiver improved by a function which automatically identifies the modulation mode from many kinds of modulation modes. Several tests were carried out for the evaluation by PC simulation, under laboratory environment, under outdoor environment. By the evaluation tests, identification probability of 90% or better was acquired at S/N = 6 dB for BPSK, S/N = 6 dB for QPSK, S/N = 6 dB for 8PSK, S/N = 6 dB for pi/4 shift QPSK and S/N = 4 dB for 16QAM. The identification probability of the proposed algorithm was almost same under both of static and dynamic environment, although the dynamic environment was influenced by fading and multipass phenomena, etc.
