This study is on radio synchronization scheme applied for Wideband Ubiquitous Mobile radio service in near future. It is pointed that required signal processing steps are increased and the process time is reduced to cover large number of mobile users. Digital processing and calculation has been used for synchronization processing, but they need much power consumption. In this study, MOS transistor based LSI processing is used base on analog calculation which omit multiplication effectively, and it also usefully composes simple processing for peak detection and demodulation of waveform signals and so on. For 4.096Mbit/s data in 5MHz band, power consumption of synchronization and demodulation are archived less 1/32 to the conventional circuit schemes, and less 1/16 to up to 12Mbit/s.

本研究是针对不久的将来应用于宽带普适移动无线电服务的无线电同步方案。需要指出的是，需要增加信号处理步骤并减少处理时间以覆盖大量移动用户。数字处理和计算已用于同步处理，但它们需要很大的功耗。本研究采用基于MOS晶体管的LSI处理，以模拟计算为基础，有效地省略了乘法运算，并且还有效地构成了峰值检测、波形信号解调等简单处理。对于5MHz频段4.096Mbit/s的数据，同步和解调的功耗比传统电路方案低1/32，低1/16，最高可达12Mbit/s。
