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

A Simple Two-Stage Equalizer for OTFS With Rectangular Windows
TL;DR: In this paper, the authors proposed a two-stage equalizer, wherein received signals are judiciously processed in two domains, and a sliding window-assisted minimum mean square error (SW-MMSE) equalizer is proposed to restrict the intercarrier interference effectively.

Systems and methods for variable thresholding in a pattern detector
TL;DR: In this paper, a pattern detection circuit is discussed that includes a distance calculation circuit, a threshold comparator circuit, and a threshold value calculation circuit that is operable to modify the variable threshold value based at least in part on the distance value.

An Interference Nulling Based Channel Independent Precoding for MIMO-OFDM Systems with Insufficient Cyclic Prefix
Yuansheng Jin,Xiang-Gen Xia +1 more
TL;DR: It is shown that the proposed channel independent precoding scheme can eliminate the inter-block interference (IBI) caused by the insufficient CP with higher bandwidth efficiency than the conventional zero-padded or a sufficient CP added block transmission system when nr ≤ nt.

Performance of an Efficient Parallel Data Transmission System
TL;DR: A parallel quadrature AM data transmission system with a number of overlapping channels, each carrying a signaling rateb, spacedb/2apart in frequency appears to be a promising technique for achieving good performance at high information rates over bandlimited dispersive transmission media.
