Abstract:
In this paper, a novel protocol to mitigate co-channel interference issue acquiring higher diversity gain is introduced in Multiple Input Multiple Output (MIMO) femto cell environment. The scheme works under three time slots using Alamouti Space–time block code (STBC) and MIMO gains to achieve full diversity order of four. A network based on wireless access consists of two femto users points, and destination terminals as femto base stations each equipped with two antennas respectively. The performance is analyzed using 16-Quadrature Amplitude Modulation (QAM) modulation scheme. The results are investigated over independent and identical (i.i.d) fading channel. Subsequently, the obtained results by simulation show that the proposed novel transmission protocol provides interference mitigated and better signal quality of uplink femto users in cooperative wireless networks.
