摘要： A check matrix generation method for generating a check matrix H1 of a code H1 from a check matrix H0 of a code C0, where codes C0 and C1 are LDPC systematic codes having different encoding ratios in a rate-compatible relationship and information bit sizes of the systematic codes C0 and C1 are K, and parity bit sizes thereof are M0 and M1 (M1−M0=L) respectively. The method comprising steps of: selecting L number of rows out of the check matrix H0; separating an information bit portion and a parity bit portion constituting each of the selected rows into two respectively, such that each of the separated information bit portions includes one or more non-zero elements which are “elements different from 0”; creating a new first row by coupling one separated information bit porting and one separated parity bit portion and creating a new second row by coupling another separated information bit portion and another separated parity portion; and generating the check matrix H1 of the systematic code C1 by placing the new first and second rows in place of each of the selected L number of rows in the check matrix H0.

摘要： A transmission circuit transmits a connection request including a “signature” to a base station. The demodulator demodulates the AICH for transmitting a notification corresponding to the connection request. When requested communications are enabled, the AICH transmits the “signature”. A multiplier multiplies a demodulation signal by the “signature”. A voltage computation unit converts the output of the multiplier into a voltage value. An integrator integrates the voltage value computed by the voltage computation unit for each received symbol for the respective symbols corresponding to the “signature”. A threshold generation unit adaptively selects one of a threshold determined based on the noise of a transmission path or a threshold determined based on the receiving power. If the output of the integrator is larger than the selected threshold, it is determined that the communications have been enabled.

摘要： In a wireless communication method, a first wireless communication apparatus transmits through a first wireless resource to a second wireless communication apparatus a first signal generated from a second signal for use in processing performed by the second wireless communication apparatus and a third signal for use in error checking of the second signal. The second wireless communication apparatus detects a second wireless resource to be used in the processing on the basis of the first signal, and performs the processing by using the second signal and the detected second wireless resource. For the detection, a section of the first signal corresponding to the second wireless resource is scrambled, or the first signal is scrambled with a scrambling sequence corresponding to the second wireless resource, or the bit order in at least part of the first signal is changed in a manner corresponding to the second wireless resource.
