An Integrated OFDM Receiver for High-Speed Mobile Data Communications
Overview This paper presents the system design of an integrated receiver for the next generation high-speed mobile data communications based on OFDM. An overview of the OFDM system suitable for mobile communications is described. The effects of non-ideal transmission conditions of the OFDM system including channel estimation errors, symbol timing offset, carrier and sampling clock offset, phase noise and time-selective fading are analyzed.

Mutual Interference in OFDM-Based Spectrum Pooling Systems
Public mobile radio spectrum has become a scarce resource while wide spectral ranges are only rarely used. Here, a new strategy called spectrum pooling is considered. It aims at enabling...
Design and Simulation of Orthogonal Frequency Division Multiplexing (OFDM) Signaling
A MATLAB program has been written to investigate Orthogonal Frequency Division Multiplexing (OFDM) communication systems. This program is valuable for future researchers simulating systems that are too theoretically complex to...
V.92 The Next Generation Modem Technology
The paper discusses the features and benefits of V.92. As with any new standard, multi-vendor interoperability is critical to help accelerate deployment of standards-based equipment. Lucents V.92 solution inter-operates with...
Effect of Rounding and Saturation in Fixed-Point DSP Implementation of IFFT and FFT for OFDM Applications
This paper describes a new technique for designing FFTs for Orthogonal Frequency Division Multiplex (OFDM) transmitters and receivers. Using the new technique, signals within the FFT structure are scaled so...
Optimum Noise Thresholds in Decision Directed Impulse Noise Mitigation for OFDM
Impulse noise is a significant problem in some OFDM applications including digital television broadcasting. This paper studies the optimum threshold values for a novel decision directed impulse noise mitigation algorithm....
