Performance of OFDM with Blind Interference Suppression Schemes

In statistical wireless signal processing, extraction of unobserved signals from observed mixtures can be achieved through Blind Source Separation (BSS) algorithms. Orthogonal Frequency Division Multiplexing (OFDM) can be pronounced as one of the predominant multicarrier air interface communication technique. Consequence of an effort taken to diminish the undesirable influences encountered with in the wireless interface of an OFDM system with the help of a BSS scheme based counteractive solution is disclosed by this paper. Filter coefficients that are employed at the receiver are ascertained with the support of energy functions and the iterative fixed point rule. Time correlation properties of the channel are taken advantage for BSS. Performance of the algorithm when it is used for an OFDM model is evaluated under slow fading channel conditions with a receiver containing Equal Gain Combining (EGC). The importance is that, this scheme can be lead to low complexity mechanisms.
