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

Coordinated MultiPoint transmission in LTE-Advanced femtocell networks
TL;DR: A CoMP scheme is proposed where the transmitter’s packets are received simultaneously at different Evolved Node Bs (eNodeB) via a high speed link, which processes the signals with the multiple copies of the messages received.

Antenna Doping: A Countermeasure Against MIMO Spatial Correlation
TL;DR: This paper incorporates a so-called antenna doping (AD) scheme into the SM system, in order to further counteract the detrimental effects of spatial correlation, and shows that AD can improve the performance by 3-4 dB in severe spatial correlation as compared to non-doping systems.
