Abstract
Disclosed herein are a method for channel decoding using noise level correction in a high-speed mobile reception environment and an apparatus for the same. The method includes estimating, by a signal receiver that is based on OFDM and is moving at high speed, Inter-Carrier Interference (ICI) power for received signal power based on the movement speed of the signal receiver; calculating, by the signal receiver, a Signal-to-Noise Ratio (SNR) for a received signal using an estimate of the ICI power; and decoding, by the signal receiver, a channel code based on a Log Likelihood Ratio (LLR) per bit, calculated based on the SNR, and the received signal.
