  • A comparison of full-rate full-diversity 2x2 space-time codes for WiMAX systems
    Sezginer, Serdar; Sari, Hikmet; Biglieri, Ezio (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    Multiple-input multiple-output (MIMO) techniques have become an essential part of broadband wireless communications systems. For example, the recently developed IEEE 802.16e specifications for broadband wireless access ...
  • NOMA-2000 vs. PD-NOMA: an outage probability comparison
    Coşandal, Ismail; Koca, Mutlu; Biglieri, Ezio; Sari, Hikmet (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Non-orthogonal multiple access (NOMA) is an emerging technique promising to accommodate the increasing data rate requirements of next generation networks. In power-domain (PD) NOMA, this challenge is addressed by allocating ...
  • On high-rate full-diversity 2x2 space-time codes with low-complexity optimum detection
    Sezginer, Serdar; Sari, Hikmet; Biglieri, Ezio (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    The 2×2 MIMO profiles included in Mobile WiMAX specifications are Alamouti’s space-time code (STC) fortransmit diversity and spatial multiplexing (SM). The former has/nfull diversity and the latter has full rate, but neither ...
