摘要
信道化是前端接收子系统的一部分,用于区分不同的用户或信道。现代信道化采用先进的多项滤波器组来同时处理多个信道,允许同时下变频、降采样和滤波。由于传统硬件的限制,在信道数和吞吐量方面限制很大。本文基于GPU技术,将多相滤波数学模型映射到并行计算单元,实现了具有多信道、高吞吐量等特征的信道化方法,并在短波系统中验证使用。
A channelizer is a part of a receiver front-end subsystem, that separates different users or channels. A modem channelizer uses advantages of polyphase filter banks to process multiple channels at the same rime, allowing down conversion, downsampling, and filtering all at the same time. However, due to limitations imposed by hardware, there are disadvances in the count of channels and throughput. This paper uses GPU, provides a multi-channel, high-throughput of channelizer, that is uesed in HF reciver system.
