In most multiple-input multiple-output (MIMO) systems, the family of waterfall error curves,
calculated at different spectral efficiencies, are asymptotically parallel at high signal-to-noise …

Linear equalizers (LEs) have been widely adopted for practical systems due to their low
computational complexity. However, it is also well known that LEs provide inferior …

Orthogonal frequency division multiplexing (OFDM) is a practical broadband signaling
technique for use in multipath fading channels. Over the past ten years, research has shown …

Vector Orthogonal Frequency Division Multiplexing (OFDM) for single transmit antenna
systems is a general transmission scheme, where OFDM and Single-Carrier Frequency …

This paper analyzes the diversity gain achieved by single-carrier frequency-domain
equalizers (SC-FDE) in frequency selective channels, and uncovers the interplay between …

In this paper, we consider sparse index multiple access for uplink random access in a
wireless system of a number of devices when a fraction of them are active. This multiple …

Single-carrier (SC) block transmission with cyclic prefix (CP) is a method with several
advantages that has been incorporated into standards. This paper investigates the …

This paper investigates the performance of the zero-forcing (ZF) and minimum mean-square
error (MMSE) equalizers in MIMO frequency selective channels under zero-padding (ZP) …

This paper presents a novel matched rotation precoding (MRP) scheme to design a rate one
space-frequency block code (SFBC) and a multirate SFBC for MIMO-OFDM systems with …

Orthogonal frequency‐division multiplexing (OFDM) suffers from spectral nulls of frequency‐
selective fading channels. Linear precoded (LP‐) OFDM is an effective method that …
