| Abstract(in English) | A variable rate data transmission and blind rate detection scheme is proposed for coherent DS-CDMA mobile radio. The data to be transmitted is first transformed into a QPSK symbol sequence, then multiplied by the rate-matched repetition code of "1, -1", and finally spread over a wide bandwidth. At the receiver, the received signal is despread by a matched filter. The despread signal sample sequence is then multiplied by a repetition code of detected rate to recover the original transmitted QPSK symbol sequence. The probability of rate detection error for a 4-rate case and the frame error rate performance are evaluated by computer simulations in a 2-path Rayleigh fading channel. |
