Description
Discrete-time signal processing has had a momentous impact on advances in engineering and science over recent decades. The rapid progress of digital and mixed-signal integrated circuits in processing speed, functionality and cost-effectiveness has led to their ubiquitous employment in signal processing and transmission in diverse milieux.
The absence of training or pilot signals from many kinds of transmission – in, for example, speech analysis, seismic exploration and texture image analysis – necessitates the widespread use of blind equalization and system identification. There have been a great many algorithms developed for these purposes, working with one- or two-dimensional (2-d) signals and with single-input single-output (SISO) or multiple-input multiple-output (MIMO), real or complex systems. It is now time for a unified treatment of this subject, pointing out the common characteristics and the sometimes close relations of these algorithms as well as learning from their different perspectives. Blind Equalization and System Identification provides such a unified treatment presenting theory, performance analysis, simulation, implementation and applications.
Topics covered include:
• SISO, MIMO and 2-d non-blind equalization (deconvolution) algorithms;
• SISO, MIMO and 2-d blind equalization (deconvolution) algorithms;
• SISO, MIMO and 2-d blind system identification algorithms;
• algorithm analyses and improvements;
• applications of SISO, MIMO and 2-d blind equalization/identification algorithms.
Each chapter is completed by exercises and computer assignments designed to further understanding and to give practical experience with the algorithms discussed.
This is a textbook for graduate-level courses in discrete-time random processes, statistical signal processing, and blind equalization and system identification. It contains material which will also interest researchers and practicing engineers working in digital communications, source separation, speech processing, image processing, seismic exploration, sonar, radar and other, similar applications.

描述
離散時間信號處理在過去幾十年對工程和科學的進步產生了重大影響。數字和混合信號集成電路在處理速度、功能和成本效益方面的快速進展,導致它們在不同環境中的信號處理和傳輸中被廣泛使用。
許多種類的傳輸中缺乏訓練或導引信號,例如語音分析、地震勘探和紋理圖像分析,這就需要廣泛使用盲等化和系統識別。已經開發了許多算法來實現這些目的,這些算法可以處理一維或二維信號,以及單輸入單輸出(SISO)或多輸入多輸出(MIMO),實數或複數系統。現在是對這個主題進行統一處理的時候了,指出這些算法的共同特點和有時的密切關係,並從不同的角度學習。《盲等化和系統識別》提供了這樣一種統一的處理,介紹了理論、性能分析、模擬、實現和應用。
涵蓋的主題包括:
- SISO、MIMO和二維非盲等化(反卷積)算法;
- SISO、MIMO和二維盲等化(反卷積)算法;
- SISO、MIMO和二維盲系統識別算法;
- 算法分析和改進;
- SISO、MIMO和二維盲等化/識別算法的應用。
每章都包含練習和計算機作業,旨在進一步理解並提供對所討論算法的實際經驗。
這是一本研究生課程的教科書,涵蓋了離散時間隨機過程、統計信號處理以及盲等化和系統識別的材料。它還將對數字通信、源分離、語音處理、圖像處理、地震勘探、聲納、雷達和其他類似應用的研究人員和實踐工程師感興趣。
