Low-Complexity Channel Estimation Using Short-Point FFT/IFFT for an Iterative Receiver in an LDPC-Coded OFDM System |
Abstract | ||
|---|---|---|
A frequency-domain channel expanding technique (FD-CET) is proposed for channel estimation in an iterative receiver of a low-density parity-check coded orthogonal frequency division multiplexing system. The FD-CET can expand a subset of the frequency-domain channel gains to all of them in a short-point FFT/IFFT format. This technique is applied to estimate the channel gains utilizing the pilots and information from the decoder in an iterative manner. It is a novel low complexity channel estimation method. Numerical results demonstrate that the proposed channel estimator approaches a maximum-likelihood performance within only a few iterations under multi-path channels. |
