Blind Interference Alignment Simulation over Rayleigh fading channel

In wireless communications, MIMO systems play major role in achieving higher data rates and reliability with spectral efficiency. In MU-MIMO systems, interference is a major concern factor to attain proper communication. Interference alignment(IA) is achieved with channel state information at transmitter, which effects on spectral efficiency. Blind Interference Alignment is a new promising technology which aligns interference in MU-MIMO systems without channel state information at transmitter(CSIT). Key feature of BIA is switching of the receive antenna among its pre-determined modes. Super Symbol creation is one of the key features for Blind Interference Alignment. This is employed at receiver with Electronically Steerable Parasitic Array Radiator(ESPAr)Antenna. ESPAR Antenna is an array antenna which has one active element at centre and other elements as parasitics around it. ESPAR Antenna works on taking advantage of mutual coupling among antenna elements. The proposed BIA technology is exploited considering cellular networks with synchronous align and non synchronous align code. In this paper, BIA technology is employed in 3×2,2×2,3×3 MIMO structures for synchronous and non synchronous alignment codes and compared with 2Xl MISO and appropriate results are produced.
