摘要： A transmission method performed by a mobile station for random access channel (RACH) burst transmission diversity gain is provided. According to the method, by combining and using switching diversity by beam forming, frequency hopping, and power ramping, the probability that when the speed of a mobile station is low, the mobile station falls into a deep fading environment is lowered, thereby increasing the probability of detecting an RACH signature of the base station. Also, by using the transmission parameters (subbands, precoding matrixes, power, etc.) which are used for successful transmission of an RACH burst, for transmission of a successive user packet data, reliable transmission of the successive user packet data can be performed.

摘要： Provided are methods for encoding and decoding low-density parity-check (LDPC) codes and a method for forming an LDPC parity check matrix. The method for forming the LDPC parity check matrix, includes the steps of: preparing a plurality of parity check matrixes; and selecting a parity check matrix having maximum performance from the prepared parity check matrixes, wherein the parity check matrix has a degree distribution G(x) that meets an equation, G ⁡ ( x ) = ∑ k = 2 d i - 1 ⁢ a k ⁢ x k + ∑ k = d i d max ⁢ C ⁢ ⁢ k - γ ⁢ x k ⁢ ⁢ or ⁢ ⁢ G ⁡ ( x ) = ⁢ ∑ k = 2 d max ⁢ C ⁡ ( k + α ) - γ ⁢ x k , where, ak is a parameter that corresponds to the probability that nodes of the graph have a degree k, C is a parameter that is determined by a normalization condition, G(1)=1, and α, γ are parameters that is optimized through numerical calculations. This may significantly decrease a time to discover an optimal code by using a power-law distribution with less parameters in designing the LDPC codes, as compared with numerical optimization in a global parameter space.
