Abstract

PURPOSE:To reduce the unevenness of compressing characteristic depending on the sample timing of signals received by addition of the number m of compressed waves obtained employing a pulse train shifted by 2pi/m in the phase as the driving clock of an analog delay element. CONSTITUTION:After received, the signal transmitted from a transmitter is phase detected to reproduce the transmitted code. The transmitted code reproduced is applied to a coded pulse compressors 11...1m of delaying elements. When the coded pulse compressor is driven by clocks CP1...CPm having a phase of 2pi/m, the compressed waves obtained Y1...Ym are added with an output adder 20. The addition allows the correction of the compressed waves due to misampling by the compressed waves of correct timing sample and the compressed output SIGMAYi is produced in the form of improved deterioration in the compressing property.
