Precoding is proved to be highly efficient to improve the bit error rate (BER) of orthogonal
frequency division multiplexing (OFDM) in frequency-selective fading channels …

This paper presents a novel technique to enhance the robustness of space-frequency block
coded (SFBC) orthogonal frequency-division multiplexing (OFDM) systems. The proposed …

We present a new multiple input multiple output (MIMO) technique, based on Walsh
Hadamard Transform (WHT) precoding, to improve the robustness of space-frequency block …

This paper addresses a novel Alamouti space frequency block decoding scheme for multiple-
input multiple-output (MIMO) and orthogonal frequency division multiplexing (OFDM) based …

Precoding in orthogonal frequency division multiplexing (OFDM) system proved to reduce
the peak-to-average power ratio (PAPR), so that it improves BER. However, from the existing …

The multiple-input single-output (MISO) technique is undoubtedly one of the most
revolutionary perspectives adapted to the second generation's DVB-T2 terrestrial standard …

This paper deals mainly with the study of the asymptotic probability density functions (PDFs)
of the outage durations of the instantaneous capacity of orthogonal space-time block code …

The goal of the future terrestrial digital video broadcasting (DVB-T) standard is to employ
diversity and spatial multiplexing in order to achieve the fully multiple-input multiple-output …

The performance of standard Alamouti space-frequency block code (SFBC) degrades in
highly frequency-selective channels since quasi static fading is required for adjacent …
