商品描述
The relative motion between the transmitter and the receiver modifies the nonstationarity properties of the transmitted signal. In particular, the almost-cyclostationarity property exhibited by almost all modulated signals adopted in communications, radar, sonar, and telemetry can be transformed into more general kinds of nonstationarity. A proper statistical characterization of the received signal allows for the design of signal processing algorithms for detection, estimation, and classification that significantly outperform algorithms based on classical descriptions of signals.Generalizations of Cyclostationary Signal Processing addresses these issues and includes the following key features:
- Presents the underlying theoretical framework, accompanied by details of their practical application, for the mathematical models of generalized almost-cyclostationary processes and spectrally correlated processes; two classes of signals finding growing importance in areas such as mobile communications, radar and sonar.
- Explains second- and higher-order characterization of nonstationary stochastic processes in time and frequency domains.
- Discusses continuous- and discrete-time estimators of statistical functions of generalized almost-cyclostationary processes and spectrally correlated processes.
- Provides analysis of mean-square consistency and asymptotic Normality of statistical function estimators.
- Offers extensive analysis of Doppler channels owing to the relative motion between transmitter and receiver and/or surrounding scatterers.
- Performs signal analysis using both the classical stochastic-process approach and the functional approach, where statistical functions are built starting from a single function of time.
商品描述(中文翻譯)
相對於發射器和接收器之間的運動會改變傳輸信號的非平穩性特性。特別是,幾乎所有在通訊、雷達、聲納和遙測中採用的調變信號所展現的幾乎週期性平穩性(almost-cyclostationarity)特性,可以轉化為更一般的非平穩性類型。對接收信號進行適當的統計特徵描述,能夠設計出在檢測、估計和分類方面顯著優於基於經典信號描述的算法的信號處理算法。《週期性平穩信號處理的概括》針對這些問題進行探討,並包括以下關鍵特點:
- 提供基礎理論框架,並附上其實際應用的詳細說明,針對廣義幾乎週期性平穩過程和頻譜相關過程的數學模型;這兩類信號在移動通訊、雷達和聲納等領域中日益重要。
- 解釋非平穩隨機過程在時間和頻率域的二階及高階特徵描述。
- 討論廣義幾乎週期性平穩過程和頻譜相關過程的統計函數的連續和離散時間估計器。
- 提供統計函數估計器的均方一致性和漸近正態性分析。
- 針對由於發射器和接收器之間及/或周圍散射體的相對運動所引起的多普勒通道進行廣泛分析。
- 使用經典隨機過程方法和函數方法進行信號分析,其中統計函數是從單一時間函數開始構建的。
