We present a differential MSK receiver with coarse frame synchronization using a RSSI (received signal strength indicator) signal and thus allowing the use of the capture phenomenon. The capture event is detected by an ML-derived circuit. Our investigations include all synchronization units allowing a tradeoff between preamble length and implementation efficiency. We provide a performance study including the effect of quantization. The results prove the suitability of our concept for a mobile communication network. >
