Abstract
A symbol timing detection method, executed in a processor, is provided where, upon detecting a symbol timing from a received signal composed of a packet having a preamble with periodically allocated symbols placed at a head of data, correlation results indicating a correlation between the received signal and a fixed pattern of the preamble are obtained, a maximum value in the correlation results are updated and held, and a timing of the maximum value is determined as a symbol timing on a condition that a maximum value currently held by the correlation peak detection unit is not updated in a symbol timing determination period having a predetermined length from the timing and that a number of occurrences of a correlation result exceeding an error detection determination threshold is smaller than a predetermined number in an error detection determination period defined within the symbol timing determination period.
