Out of Band Leakage Performance of Generalized Frequency Division Multiplexing

Ms. Chhavi Sharma, Mr. S.K Tomar, Mr. Arvind Kumar

Abstract


In this work the out of band (OOB) leakage performance of Generalized frequency division multiplexing (GFDM) with clipping and filtering technique is shown and also the effect of clipping and filtering on the bit error rate (BER) performance of GFDM signal is observed. All simulation results are performed with high power amplifier.The BER performance of the proposed scheme is compared with orthogonal frequency division multiplexing (OFDM) which is a popular modulation scheme for 4th Generation wireless communication systems.Simulation results show that out of band leakage in GFDM signal is reduced up to a large extent after applying the clipping and filtering method as compared to the OFDM signal maintaining almost equal BER performance.
