商品描述

The context for this book is to present a proficient channel estimation technique for performance improvement and complexity reduction of multiple antenna system. Matrix factorization is applied on LS estimation to reduce a full rank matrix into a simpler form in order to eliminate matrix inversion. Results indicate a significant improvement in SNR compared with LS estimation. The complexity comparison is performed in terms of mathematical operations, which shows that the approach outperforms LS estimation at a lower complexity and represents a good solution for channel estimation technique. The book also provides design and implementation of a multiple antenna system on FPGA that provides reconfigurability, resource utilization and less power consumption. The encoder design is straight forward; however, the decoder design is little tricky as it requires resource optimization. The hardware, presented in this book, utilizes the resources by adopting the technique of parallelism. The system is developed based on modular design which simplifies system design, eases hardware update and facilitates testing the various modules in an independent manner.

商品描述(中文翻譯)

本書的背景是提出一種熟練的通道估計技術,以改善多天線系統的性能並降低複雜度。透過對最小二乘(LS)估計進行矩陣分解,將滿秩矩陣簡化為更簡單的形式,以消除矩陣反演。結果顯示,與LS估計相比,信噪比(SNR)有顯著改善。複雜度比較是基於數學運算,顯示該方法在較低的複雜度下優於LS估計,並且代表了一個良好的通道估計技術解決方案。本書還提供了在FPGA上設計和實現多天線系統的方法,該系統具備可重構性、資源利用率高和較低的功耗。編碼器設計相對簡單;然而,解碼器設計則稍顯複雜,因為它需要資源優化。本書中介紹的硬體利用了平行化技術來有效利用資源。該系統基於模組化設計開發,簡化了系統設計,便於硬體更新,並促進了各模組的獨立測試。
