Title: Device and method of cdma transmission/reception
Inventor: KANETANI HIROYUKI
IPC: H04B1/7073
Filed: 2001-10-30
Abstract: PROBLEM TO BE SOLVED: To provide a CDMA transmitter/receiver, capable of decoding processing without having to calculate the channel estimation value and performing phase correction by the calculated estimation value. SOLUTION: A change-over switch 102 arranges a known symbol at the head of transmission data, at the beginning of transmission and during a prescribed period after that. A threshold calculating section 113 calculates threshold from the power of a plurality of despread symbols 120. An adding section 115 adds an despreading symbol 120 to be decoded to a despreading symbol, before one symbol obtained from a delay section 114. A code variation determining section 116 compares the power of the two symbols added in the section 115 with the threshold calculated in the section 113. When the result of comparison being less than the threshold, a code-determining section 117 uses a value obtained by reversing the result of comparison of decoding the precedent symbol by a delay section 118, as a result of decoding.  When the result of comparison is not less than the threshold, the section 117 uses the result of decoding the precedent symbol by the section 118 as the result of decoding.
