    PARALLEL COMPUTING PLATFORM FOR EVALUATING LDPC CODES PERFORMANCE حسب Alghonaim, Esa

    منشور في 2007
    "…This paper presents a novel approach for the design and implementation of a simulation platform for evaluating LDPC codes performance. The existing LDPC code simulation tools consume very long time in evaluating the performance of a specific code design. …"

    On Space–Time Coding With Pulse Position and Amplitude Modulations for Time-Hopping Ultra-Wideband Systems حسب Abou-Rjeily, Chadi

    منشور في 2007
    "…On the other hand, while the perfect codes were considered mainly with quadrature amplitude modulation (QAM) and hexagonal (HEX) constellations, IR-UWB systems are often associated with pulse-position modulation (PPM) and hybrid PPM-PAM (pulse-amplitude modulation) constellations. …"

    A Space-Time Coded MIMO TH-UWB Transceiver with Binary Pulse Position Modulation حسب Abou-Rjeily, Chadi

    منشور في 2007
    "…We consider the problem of space-time (ST) coding with binary pulse position modulation (PPM) and we propose the first known family of rate-1 ST codes that can be associated with binary PPM without introducing any additional constellation extension. …"

    An optimal 2 × 2 space-time code for time-hopping ultra-wideband systems with binary pulse position modulation حسب Abou-Rjeily, Chadi

    منشور في 2017
    "…Unlike the golden code that can be associated with all constellations carved from Zopf[i], the proposed code is optimal with binary pulse position modulation (PPM) which is a popular modulation scheme for TH-UWB. …"
