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.

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.

摘要： A low density parity check (LDPC) code generating method and apparatus are provided. A parity check matrix with (N−K) rows for check nodes and N columns for variable nodes are formed to encode an information sequence of length K to a codeword of length N. The parity check matrix is divided into an information part matrix with K columns and a parity part matrix with (N−k) columns. The parity part is divided into P×P subblocks. P is a divisor of (N−K). First and second diagonals are defined in the parity part matrix and the second diagonal is a shift of the first diagonal by f subblocks. Shifted identity matrices are placed on the first and second diagonals and zero matrices are filled elsewhere. An odd number of delta matrices each having only one element of 1 are placed in one subblock column of the parity part matrix. The parity check matrix is stored.
