This work titled A Digital Phase Locked Loop based Signal and Symbol Recovery System for Wireless Channel is intended to serve as a document covering funda- mental concepts and application details related to the design of digital phase locked loop (DPLL) and its importance in wireless communication. It documents some of the work done during the last few years covering rudimentary design issues, complex implementations, and fixing configuration for a range of wireless propa- gation conditions.

This book is intended for the graduate or advanced undergraduate engineer. The primary motivation for developing the text was to present a complete tutorial of phase-locked loops with a consistent notation. I believe this is critical for the practicing engineer who uses the text as a self-study guide.

This reference design describes the design of a 3-phase AC induction vector control drive with position encoder coupled to the motor shaft. It is based on Motorola’s DSP56F805 dedicated motor control device. AC induction motors, which contain a cage, are very popular in variable speed drives. They are simple, rugged, inexpensive and available at all power ratings. Progress in the field of power electronics and microelectronics enables the application of induction motors for high-performance drives, where traditionally only DC motors were applied. Thanks to sophisticated control methods, AC induction drives offer the same control capabilities as high performance four-quadrant DC drives.

基于TMS320F28035芯片為控制核心的空間矢量異步電機(jī)變頻器 我們?cè)O(shè)計(jì)的異步電機(jī)變頻調(diào)速器以TMS320F28035芯片為控制核心，通過(guò)輸出三相PWM波控制智能功率模塊IPM驅(qū)動(dòng)三相異步電機(jī)。我們使用空間矢量SVPWM算法，并對(duì)其進(jìn)行了優(yōu)化。采用檢測(cè)反電勢(shì)的方法省去了昂貴的光電編碼器，大大節(jié)省了成本。同時(shí)開(kāi)創(chuàng)性的研發(fā)了自動(dòng)根據(jù)運(yùn)行環(huán)境調(diào)節(jié)的自適應(yīng)變頻算法，使我們的變頻調(diào)速器可以在電網(wǎng)條件惡劣的鄉(xiāng)村山區(qū)工作，由此該變頻器已被一家民用水泵生產(chǎn)企業(yè)預(yù)訂。關(guān)鍵字 變頻器 TMS320f28035 IPM SVPWM In our design, the asynchronous machine inverter based on the chip of TMS320F28035 drives the three-Phase asynchronous machine by sending three-phase PWM waves to the IPM, which is short for the Intelligent-Power-Module. The SVPWM (space vector pulse width modulation) strategy is applied to our control algorithm and we optimize it mainly in two aspects. Firstly the inverter detects the speed by measuring the Back EMF instead of installing an expensive photoelectric encoder for costs reduction.

偏移正交相移鍵控(OQPSK：Offset Quadrature Phase Shift Keying)調(diào)制技術(shù)是一種恒包絡(luò)調(diào)制技術(shù)，具有頻譜利用率高、頻譜特性好等特點(diǎn)，廣泛應(yīng)用于衛(wèi)星通信和移動(dòng)通信領(lǐng)域。 論文以某型偵收設(shè)備中OQPSK解調(diào)器的全數(shù)字化為研究背景，設(shè)計(jì)并實(shí)現(xiàn)了基于FPGA的全數(shù)字OQPSK調(diào)制解調(diào)器，其中調(diào)制器主要用于仿真未知信號(hào)，作為測(cè)試信號(hào)源。論文研究了全數(shù)字OQPSK調(diào)制解調(diào)的基本算法，包括成形濾波器、NCO模型、載波恢復(fù)、定時(shí)恢復(fù)等；完成了整個(gè)調(diào)制解調(diào)算法的MATLAB仿真。在此基礎(chǔ)上，采用VHDL硬件描述語(yǔ)言在Xilinx公司ISE7.1開(kāi)發(fā)環(huán)境下設(shè)計(jì)并實(shí)現(xiàn)了各個(gè)算法模塊，并在硬件平臺(tái)上加以實(shí)現(xiàn)。通過(guò)實(shí)際現(xiàn)場(chǎng)測(cè)試，實(shí)現(xiàn)了對(duì)所偵收信號(hào)的正確解調(diào)。論文還實(shí)現(xiàn)了解調(diào)器的百兆以太網(wǎng)接口，使得系統(tǒng)可以方便地將解調(diào)數(shù)據(jù)發(fā)送給計(jì)算機(jī)進(jìn)行后續(xù)處理。
