MIMO OFDM Implementation in Cognitive Scenario

Rahul Gedam [3] | Dr. M. R. Meshram | Dr. A. K. Shrivastava [2]

Abstract: Cognitive, meaning concerned with the act or process of knowing, perceiving etc. cognitive radio CR is a concept of creating a software defined Radio platform for utilizing the spectrum holes which are underutilized. By smartly using the spectrum the scarcity of spectrum problem and congestion of data traffic in a network can be minimized in a very sophisticated manner. Orthogonal frequency division multiplexing is a reliable and authentic transmission system for CR system which provides us with great amount of flexibility to fully utilized the spectrum in the active mode. Dynamically using the available spectrum resources is the highlight of the paper, when we think of an efficient communication module there are various parameters which has to be accounted for e. g. mutual interference, data rate, band width utilization, bit error rate, signal to noise ratio etc. This paper presents a MIMO-OFDM structure in cognitive radio scenario, performance of proposed system is evaluated on the basis of Bit error rate (BER) and signal to noise ratio (SNR).

Keywords: Cognitive radio, OFDM, OFDM-MIMO, Bit error rate, Signal to noise ratio
