Today's wireless networks consist of a large array of mobile equipments. The communication between varieties of mobile equipments is regulated by different IEEE Standards. This paper analyses different modulation techniques used for Software defined radio. SDR technologies are important from the point of future mobile communication system because of its reconfigurable and multimode operational capabilities. The selection of modulation scheme depends on Bit Error Rate (BER), Signal to Noise Ratio (SNR), available bandwidth. The basic criteria for best modulation technique are power efficiency, better Quality of Service (QoS), cost effectiveness, bandwidth efficiency and system complexity.
