摘要： Disclosed is a method for controlling a memory in a mobile communication system. The method includes receiving certain frame control information by a Data Receiver Block (DRB) from a MAP decoder, forming a burst descriptor by the DRB by using the frame control information, and transferring the burst descriptor to a Low Medium Access Control (LMAC), and allocating a memory by the LMAC based on bursts according to the burst descriptor.

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.

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.
