Title
Orthogonal Frequency Division Multiplexing Combined Amplitude-Locked Loop System
Abstract
Orthogonal frequency division multiplexing (OFDM) is one of the major techniques in wireless communication. Message delivery process will be damaged by channels during wireless transmission, so channel estimation on received side is very important. We disregard slight carrier interferences occurring after frequency estimation and frequency offset of OFDM system have been completed, but a wrong decision-making may be brought out due to phase revolving on constellations that caused to the rest of frequency offset. In this paper adopt an OFDM combined amplitude-locked loop to suppress co-channel interference according to signal characteristics of demodulation and separate in wireless channel environment. The proposed amplitude-locked loop separation system can be implemented and combined the statistic independent characteristics and mathematics algorithm to modulate for original signals.
