New Techniques for Multicarrier Communication Systems
Common to all OFDM systems is a large peak-to-average-power ratio (PAR) problem, which can lead to low power efficiency and nonlinear distortion at the transmit power amplifier. Tone reservation uses unavailable or reserved tones to design a peak-cancelling signal that lowers the PAR of a transmit …

A Filtered Multitone (FMT) Implementation with Custom Instructions on an Altera FPGA
… However, according to a report from the Federal Communications Commission (FCC) in 2002, a different story was told : At any given time and location, much of the prized spectrum lies idle. At the same time, FCC revealed the fact that, in many bands, spectrum access is a more significant problem …

Design and Analysis of OFDM System for Powerline Based Communication
Research on digital communication systems has been greatly developed in the past few years and offers a high quality of transmission in both wired and wireless communication environments. Coupled with advances in new modulation techniques, Orthogonal Frequency Division Multiplexing (OFDM) is a …

Simulation of Adaptive Array Algorithms for OFDM and Adaptive Vector OFDM Systems
… effective against multipath distortion. It is a multicarrier communication scheme, in which the bandwidth of the channel is divided into subcarriers and data symbols are modulated and transmitted on each subcarrier simultaneously. By inserting guard time that is longer than the delay spread of …

Generalized DFT: extensions in communications
… a very limited number of sets to be used in a multicarrier communication system. In contrast, as an extension on Discrete Fourier Transform (DFT) from the linear phase to non-linear phase, the proposed GDFT provides many possible carrier sets of various lengths with comparable or better …
