Abstract

In SDR, it is advantageous if the data is transmitted using the best among the various modulation techniques with respect to SNR. The receiver has the ability to automatically identify the modulation technique and demodulate it. This process involves a novel method where a pilot sequence helps in identifying the type of modulation at the receiver. Ten modulation techniques are used in this study and their performance is studied. Further, error detection and correction is done to the received data using hamming encoder. This study also discusses about the error handling capability and detection of the position in which the error occurs. This work can be implemented in remote locations and in emergency situations where a particular modulation technique is used based on the available QoS.
