摘要
Described is an one bit matched filter for generating a sequences of correlations between a signal bit stream and a sample stream of n sample bits. The n sample bits are arranged in a rang of n bit positions n, n-1, . . . , 2, 1. Among the n sample bits, m boundary positions are defined based on the bit pattern of the sample stream, where m n. At a specific time T(k), the m boundary positions are used to generate a Contribution (k) for a section of signal bits that are shifted into the n bit positions. At the time T(k), a Correlation (k) is generated by adding the Contribution (k) with the Correlation (k-1) that was generated at the previous time T(k-1).
