TLDR
The authors discuss the potential of OFDM signaling, with its limitations and inherent problems, as well as another potential technique that has so far been overlooked: single-carrier transmission with frequency- domain equalization, and introduces coded-OFDM (COFDM), which makes use of channel coding and frequency-domain interleaving.Abstract:
The authors discuss the potential of OFDM signaling, with its limitations and inherent problems, as well as another potential technique that has so far been overlooked: single-carrier transmission with frequency-domain equalization. The carrier synchronisation issue is dealt with before the authors introduce coded-OFDM (COFDM), which makes use of channel coding and frequency-domain interleaving. >read more

Effective ICI matrix and its compensation in SCFDMA communication system
P M Deepak,C. K. Ali +1 more
TL;DR: SCFDMA system is analysed in the presence of CFO and the results of analysis are utilized in framing an efficient representation to the multidimensional frequency synchronization problem as effective ICI matrix and a method to jointly compensate effective ICi matrix and equalize the channel is proposed based on minimum mean square error criterion.

Unit Tap Constrained Adaptive Channel Shortening Equalization
TL;DR: This paper uses the use of a unit-tap constraint to manipulate existing algorithms into a framework analogous to the recursive least squares algorithm, and develops adaptation rules for blind and semi-blind frequency domain equalizers for SCCP receivers.

Fixed Point Decoding Performance of Short-Length Structured LDPC Codes for SC-FDE Based 60-GHz WPAN (IEEE 802.15.3c)
TL;DR: Evaluated the 576- length structured LDPC codes in SC-FDE system and found they have very good fixed point decoding performance and are very promising in supporting ultra high-data-rate transmission with low complexity in 60-GHz WPAN (IEEE 802.15.3c).

Analysis and Simulation of a Digital Mobile Channel Using Orthogonal Frequency Division Multiplexing
TL;DR: The analysis and simulation of a technique for combating the effects of multipath propagation and cochannel interference on a narrow-band digital mobile channel using the discrete Fourier transform to orthogonally frequency multiplex many narrow subchannels, each signaling at a very low rate, into one high-rate channel is discussed.
