Abstract
A high-capacity and wide coverage cell station (CS) for PHS has been developed. The developed CS employs a modified coherent demodulator with 4-branch MRC diversity and a burst-by-burst AFC to enhance the coverage. The proposed burst-by-burst AFC, which eliminates frequency errors of slotted random access signals, flattens the BER performance of the uplink control channels regardless of the carrier frequency errors. The proposed coherent demodulator achieves BER of 10-2 at received signal strength=2 dBμV in the uplink traffic channels. The developed CS also employs an antenna-sharing diversity transmission to incorporate three transmitters in a small unit with a high power efficiency. The developed CS can be applied not only for personal communication services but also wireless local loop services.
