Blind rate detection algorithm in W-CDMA mobile receiver

One of the key technologies introduced in the W-CDMA system is blind rate detection in the multi-rate service environment. One such detection scheme, the blind transport format detection (BTFD) scheme, is studied. From the performance study of FER (frame error rate) and FDR (false detection rate), it was found that the performance of BTFD without transmission rate information was almost equal to that of detection with a priori transmission rate information in W-CDMA system.
