Frequency domain equalization for single-carrier broadband wireless systems
TLDR
This article surveys frequency domain equalization (FDE) applied to single-carrier (SC) modulation solutions and discusses similarities and differences of SC and OFDM systems and coexistence possibilities, and presents examples of SC-FDE performance capabilities.Abstract:
Broadband wireless access systems deployed in residential and business environments are likely to face hostile radio propagation environments, with multipath delay spread extending over tens or hundreds of bit intervals. Orthogonal frequency-division multiplex (OFDM) is a recognized multicarrier solution to combat the effects of such multipath conditions. This article surveys frequency domain equalization (FDE) applied to single-carrier (SC) modulation solutions. SC radio modems with frequency domain equalization have similar performance, efficiency, and low signal processing complexity advantages as OFDM, and in addition are less sensitive than OFDM to RF impairments such as power amplifier nonlinearities. We discuss similarities and differences of SC and OFDM systems and coexistence possibilities, and present examples of SC-FDE performance capabilities.read more

Analysis of the Impact of Nonlinearity on the Capacity of Communication Channels
TL;DR: This analysis is based on a general transmission model that includes transmitter and receiver nonlinearities, environmental thermal noise, and receiver chain noise and derives lower and upper bounds for the channel capacity of additive white Gaussian noise channels, fading channels, and multiple input multiple output channels in various thermal noise and receiver noise regimes.

Multiuser Detection for Asynchronous Broadband Single-Carrier Transmission Systems
TL;DR: This paper proposes a novel multiuser detection (MUD) technique that can separate the signals, regardless of the arrival timing differences between the MTs, and the technique can suppress the effect of the IBI while retaining a low complexity level.

Method of equalising two signals transmitted with different radio transmission methods and corresponding radio communication system and receiver
TL;DR: In this article, a wireless communication system has at least one transmitter (MS) and receiver (BS), with the transmitter sending first signals (S1) to receiver by orthogonal frequency domain multiplexing (OFDM), the receiver determines first parameters for first signal equalising.
