摘要: A complex base band signal b of a send from mobile station the CDMA system is obtained, then portion normalized in amplitude, and synchronized with PN code time reference estimated. frequency error estimated correlation value used for estimation reference. The corrected corresponding to error, estimate correct initial phase. are lag between symbol point sample nearest thereto displaced by generated. remaining phase least squares method. All values b, calculate waveform quality.
