Filtered decision feedback channel estimation for OFDM-based DTV terrestrial broadcasting system
TL;DR: This paper presents an application of a filtered decision feedback channel estimator for OFDM-based DTV systems using high order QAM modulations and the implementation and the performance of the channel estimators are discussed.
Journal ArticleDOI
Hardware nonlinearities in digital TV broadcasting using OFDM modulation
TL;DR: The paper investigates the in-band and out-of-band behaviour of a 64QAM-OFDM system under various nonlinear devices and shows that the inherent signal clipping in the IFFT processors with a limited word length reduces the required RF amplifier output backoff (OBO) where adjacent channel interference is the limiting factor.
Proceedings ArticleDOI
A discrete multi carrier multiple access technique for wireless communications
TL;DR: A discrete multi carrier multiple access (MCMA) technique is proposed for multi user wireless communications where an interleaved set of subcarriers is dedicated to each user to provide with a high order of frequency diversity.
Proceedings ArticleDOI
On the performance of a coded MCM over multipath Rayleigh fading channels
TL;DR: It is shown that the system performance meets and in some cases exceeds the matched-filter bounds provided that a proper channel coding and interleaving is used.
Proceedings ArticleDOI
Multi carrier modulation for indoor wireless communications
TL;DR: The average Bit Error Rate (BER) performance is at best similar to the performance achievable over flat Rayleigh fading channels if no channel coding is used, and block error rate results are presented and used in predicting the average performance improvement due to linear block codes.
