Features: This book systematically discusses the fundamental theories and implementation techniques of all-digital receivers, providing a necessary foundation for the development of all-digital demodulation in all-digital receivers, including HDTA, CDMA, TDMA, third-generation mobile communication systems, and software radio systems. An all-digital receiver converts the carrier signal into a digital signal at the front-end of the receiver, such as in the intermediate frequency, high frequency, or near the receiving antenna, using an analog-to-digital converter (A/D conversion). All subsequent functions of the receiver (such as down-conversion, filtering, and demodulation) are implemented using digital processing techniques. It is a product of the integration of communication technology, computer technology, and large-scale digital integrated circuit technology. It has fundamentally transformed the structure, functionality, and development methods of receivers. The content of this book includes efficient digital modulation techniques, the structure of all-digital receivers, maximum likelihood receivers, time-varying interpolation filters, synchronization parameter estimation algorithms, digital down-conversion, and the hardware structure of all-digital receivers. This book can be used as a reference for engineering technicians engaged in communication, mobile communication, electronic information industry, especially those involved in the research and development of new communication systems. It can also be used as a teaching material for students and teachers in colleges and universities majoring in communication, electronics, computer science, and related fields, or as a graduate textbook.
