以數位訊號處理器為架構之智慧型天線接收機雛形實現

Abstract

本論文以數位訊號處理器為基礎，配合到達角度估測（DOA）理論及波束形成理論（Beam forming）之需要，研究在多顆數位訊號處理器之間、個人電腦與數位訊號處理器之間，快速資料傳送、溝通之方法，並實作一個適合陣列訊號處理之高運算量分散式運算處理平台雛形。此外，為克服多路天線接收裝置之龐大結構與設備要求，本論文參考RUSK通道聽取器（Channel Sounder）相似方法，以通道掃瞄機制之技巧實作多天線單路設備接收裝置，以達到改良前端接收裝置之目的。本平台以個人進接通訊系統（Personal Access Communication System，PACS）為發展、實驗之通訊系統，實作一智慧型天線接收機（Smart Antenna Receiver）雛形。

This thesis focuses on using multiple DSPs (Digital Signal Processor) architecture, while satisfying the design requirements based on the DOA（Direction-of-Arrival）Theory and the Beam Forming Theory, to achieve fast data transfer and communication method between DSP and DSP or DSP and PC. A prototype of computing platform is implemented with high computing power to be applicable for array signal processing. Moreover, in order to overcome the huge structure and device requirement of the multi-channel receiving equipments, a similar method with the RUSK channel sounder was referred to obtain improvements in the front-end receiving device. Using the skill of channel scanning, a multi-antenna receiving device with single path equipment is realized. The platform develops a smart antenna receiver prototype on PACS.
