Adaptive Receiver Systems Implementation on Parallel Processing Systems

本计画研究无线电通讯之适应性接收器之发展，其演算法及其在平行处理装置上之执行。接收器将其波束方向图转向一个或多个感兴趣的信号，同时使干扰器“归零”的能力是工作的重点。该方案是基于一个多元素的接收器，和先进的数字信号处理（DSP）算法，自适应控制的视线方向。特别是随着无线通信的趋势是朝向更高的数据速率和移动性程度，响应于变化的环境而快速调整波束图案的能力是重要的研究领域。自适应算法，可能在高采样率下工作，是必需的，这导致需要在高速并行计算平台上实现。因此，固定点实现，计算调度和其他实现问题等主题将与算法研究一起进行研究。

This project investigates the development of adaptive receivers for wireless radio communications, in terms of algorithms and their implementation on parallel processing devices. The ability of a receiver to steer its beam pattern towards one or more signal(s) of interest, while simultaneously 'nulling' interferers, is the focus of the work. The scenario is based on a multi-element receiver, and advanced Digital Signal Processing (DSP) algorithms to adaptively control the look direction. Particularly as the trend in wireless communications is towards higher data rates and degrees of mobility, the ability to rapidly adapt the beam pattern in response to changing environments is an important area of research. Adaptive algorithms, potentially operating at high sampling rates, are required, which leads to the need for implementation on high speed, parallel computing platforms. Themes such as fixed point implementation, scheduling of computation, and other implementation issues will therefore be investigated alongside algorithmic research.
