Variable rate data transmission with blind ratedetection for coherent DS-CDMA mobile radio

Yukihiko Okumura, Fumiyuki Adachi

Abstract

A variable rate data transmission scheme with blind rate detection is described for pilot-symbol-assisted coherent DS-CDMA mobile radio. Cyclic redundancy check (CRC) coding and decoding is used for blind rate detection. Computer simulations of eight-rate variable rate data transmission demonstrate that when 16 bit CRC is used, the loss in required total Eb/N0 at a frame error rate of 10-2 under two-path Rayleigh fading, is only ~0.1 dB from the known rate case.
