Orthogonal frequency-division multiplexing (OFDM) entry schemes have gotten extra frequent between mobile and instant broadband platforms, accelerating the necessity for smaller, extra power effective receiver options. in past times the vast majority of OFDM texts have handled sign processing points. to deal with the present hole in OFDM built-in circuit (IC) guide, Chiueh and Tsai have produced this well timed textual content on baseband layout.
OFDM Baseband Receiver layout for instant Communications covers the gamut of OFDM know-how, from theories and algorithms to architectures and circuits. Chiueh and Tsai provide a concise but finished examine electronic communications basics prior to explaining modulation and sign processing algorithms in OFDM receivers. furthermore, the authors provide unique therapy of matters -- from layout method to actual IC implementation.
- Closes the space among OFDM idea and implementation
- Enables the reader to
- transfer verbal exchange receiver recommendations into hardware
- design instant receivers with applicable implementation loss
- achieve low-power designs
- Contains a variety of figures to demonstrate techniques
- Features concrete layout examples of MC-CDMA platforms and cognitive radio applications
- Presents theoretical discussions that concentrate on thoughts instead of mathematical derivation
- Provides a much-needed unmarried resource of fabric from various papers
Based on target fabrics for a category in electronic conversation IC layout, this publication is perfect for complicated undergraduate or post-graduate scholars from both VLSI layout or sign processing backgrounds. New and skilled engineers in engaged on algorithms or for instant communications units also will locate this e-book to be a key reference.
