Abstract:
An order-ensemble searching unit classifies a distribution of reception signals at each bit position of a modulation symbol, and searches an order ensemble of a parity check matrix that minimizes an SNR threshold value. A code generating unit generates a parity check matrix and a generation matrix, based on the order ensemble obtained as a search result.
