摘要

一种新的差分正交相移键控调制解调器- lsi采用差分映射调制和基带延迟检测器逻辑解调。该LSI在3v电源下，最大比特率可达85mbps以上，在80mbps时功耗低至67mw。我们构建了一个由新型调制解调器- lsi组成的中频部分测试电路，并在中频返回处进行了传输测试。该电路在75mbps时的C/N衰减约为1.7 dB。

A 85 Mbps low-power DQPSK modem-LSI for advanced wireless access

A new differential quadrature phase shift keying modem-LSI uses differential mapping for modulation and baseband delay detector logic for demodulation. The LSI achieves a maximum bit rate of over 85 Mbps and low power dissipation of 67 mW at 80 Mbps with a 3-V power supply. We built an intermediate-frequency (IF)-part test circuit composed of the new modem-LSI, and did a transmission test at IF return. The C/N degradation of this circuit is about 1.7 dB at 75 Mbps.
