ABSTRACT:
A transceiver signal processor for a digital cordless communication apparatus adopts a heterodyning loop in order to improve the transmitting circuit and power efficiency. The transceiver signal processor adopts an orthogonal demodulation method for a first intermediate frequency, thereby allowing a single reference loop. Since the reference loop itself need not be switched, a frequency drift problem is fundamentally removed.
