Abstract :
This paper demonstrated that the multi-channel signal in frequency modulation (FM) which are separated by using the phase-locked loop (PLL) and the amplitude-locked loop (ALL) algorithm. The method does not require coding process from modulation, when signals are conveyed by multi-channel transmission. For convenient analysis, we used the discrete model to represent the transmitted signals. The algorithm also can be suppressed the multi-channel interference of the additive white Gaussian noise (AWGN), when receiver signals are demodulated by the least-mean square (LMS) algorithm. From the simulation result, the separation signals of the multi-channel can be obtained the prefect performance for the criteria of the mean square error (MSE).
