Co-Efficient Vector Based Differential Distributed Quasi-Orthogonal Space Time Frequency Coding
Nwanekezie, Nnamdi; Simpson, Oluyomi; Owojaiye, Gbenga; Sun, Yichuang (2023-08-30)Distributed space time frequency coding (DSTFC) schemes address problems of performance degradation encountered by cooperative broadband networks operating in highly mobile environments. Channel state information (CSI) ... -
Efficient space-frequency block coded pilot-aided channel estimation method for multiple-input-multiple-output orthogonal frequency division multiplexing systems over mobile frequency-selective fading channels
Delestre, Fabien; Owojaiye, Gbenga; Sun, Yichuang (2014-04-17)An iterative pilot-aided channel estimation technique for space-frequency block coded (SFBC) multiple-input multiple-output orthogonal frequency division multiplexing systems is proposed. Traditionally, when channel ... -
Quasi-orthogonal space-frequency coding in non-coherent cooperative broadband networks
Owojaiye, Gbenga; Delestre, Fabien; Sun, Yichuang (2014-04-01)So far, complex valued orthogonal codes have been used differentially in cooperative broadband networks. These codes however achieve less than unitary code rate when utilized in cooperative networks with more than two ... -
Source-assisting strategy for differential distributed space time block codes
Nwanekezie, Nnamdi; Owojaiye, Gbenga; Sun, Yichuang (Institute of Electrical and Electronics Engineers (IEEE), 2013-12-01)In this paper, a source-assisting differential distributed space time block coding (SA-DDSTBC) scheme is proposed for cooperative networks. Firstly, in most existing works on distributed space time block coding (DSTBC), ... -
STBC Based Pilot-Aided Channel Estimation Method for SFBC-OFDM Systems
Delestre, Fabien; Owojaiye, Gbenga; Sun, Yichuang; El Cheikh, Mohamad (Liverpool John Moores University, 2014-06-23)In this paper, an iterative channel estimation algorithm with joint detection is proposed for Multiple Input Multiple Output (MIMO) systems combined with Orthogonal Frequency Division Multiplexing (OFDM) also known as ... -
A Systematic Study of the Behaviour of PMEPR in Relation to OFDM Design Parameters
Owojaiye, Gbenga; Sun, Yichuang; Alinier, Nandini; Simpson, Oluyomi (2011)The design of systems with enhanced quality of service (QoS) and improved power efficiency has evolved into an intensive research area in wired and wireless communications engineering. Orthogonal frequency division ...
