摘要
提出了一种用于认知无线电系统的4通道多相滤波器。认知无线电系统可以感知频谱利用率，实现更高的传输效率。为了使接收机的动态范围最大化，认知无线电接收机需要采用多通道多相滤波器来抑制传统用户产生的干扰。该滤波器能够根据系统的需要选择不同的通道。该芯片采用0.18 μ m CMOS技术制造。它的功耗为13.4 mW，相邻信道抑制为35 db。
A 4-Channel Poly-Phase Filter for Cognitive Radio Systems
A 4-channel poly-phase filter is proposed for cognitive radio systems. The cognitive radio system can sense the spectrum utilization and achieve higher transmission efficiency. To maximize the dynamic range of the receiver, the multi-channel poly-phase filter is required in the cognitive radio receiver to suppress the interference that is typically generated by legacy users. The filter is able to select different channels according to the demand of the system. A chip is fabricated in 0.18-mum CMOS technology. It dissipates 13.4 mW and achieves 35-dB adjacent channel rejection.
