Title: M-ary spread spectrum demodulator
Inventor: TAKEUCHI YOSHIHIKO
IPC: H04W88/02
Filed: 1997-11-20
Abstract: PROBLEM TO BE SOLVED: To provide an M-ary spread spectrum demodulator where deterioration of data discrimination hardly takes place. SOLUTION: A spread spectrum signal received by an antenna 10 and amplified in an LNA12 is converted into an intermediate frequency in a mixer 14 and fed to a matched filter 16. The matched filter 16 having a detection circuit provides a correlation output after detection. Every 8 correlation outputs are divided into two blocks and an averaging circuit 30 calculates a mean value for each block. Furthermore, a weighting circuit 32 applies weighting to each block, based on a ratio of the mean value to each correlation output. A comparator circuit 34 compares correlation outputs with a weighted word so as to decide a selected code. Even on occurrence of inter-chip interference, the effect is negligible to a block including codes to be selected. The effect of inter-chip interference is reduced by means averaging to a block where the selected code is not included.  As a result, a demodulation error of data is suppressed.
