Abstract

A maximum a posteriori blind bit-rate detector is derived for a fixed frame-length multiple-access system which employs variable-gain transmitter power and repetition encoding. Blind bit-rate detectors are derived for the additive white Gaussian noise channel and for the slowly fading Nakagami-m channel, assuming infinite depth interleaving at the smallest bit rate. The performances of the detectors are assessed for different frame lengths, signal-to-noise ratios, and fading conditions.
