摘要： A method and apparatus are provided where a neighbor cell interference signal is canceled upon receiving a signal transmitted from a serving base station (BS) in a receiver of an Orthogonal Frequency Division Multiple Access (OFDMA) system. The interference signals are detected from signals received from neighbor BSs and a serving BS. The strength of the detected interference signals is measures, and a determination is made whether the measured strength is higher than a threshold value. A list of neighbor BSs satisfying the determination result is reordered, and interference signals in order of the reordered neighbor BSs are selected and detected. An interference/noise variance for the detected interference signal is calculated and normalized. The normalized interference signal is decoded and regenerated, and the regenerated interference signal is subtracted from the received signal.

摘要： An apparatus and method are provided for normalizing input soft metric to a channel decoder in a wireless communication system. A demapper generates soft metric using an in-phase component (Xk) and a quadrature component (Yk) of a received modulated symbol (Rk), a channel fading coefficient (gk) and a constant value (c) defined by a modulation order of the received modulated symbol. A normalizer receives the soft metric, computes a normalized log likelihood ratio (LLR) by multiplying the soft metric by a ratio of the constant value to a noise variance value, transforms the normalized LLR into a desired range and a desired number of bits, and outputs an input LLR of the channel decoder.
