This paper discusses the implementation of an OFDM in wireless communication. Orthogonal frequency division multiplexing (OFDM) is a technique of encoding digital data on multiple carrier frequencies. OFDM is mainly chosen modulation technique for wireless communication. In OFDM scheme, large number of orthogonal, narrow band subchannels or sub carriers transmitted in parallel, divides the transmission band width. The separation of sub carriers is theoritically negligible such that there is an compact spectral utilization. The bit error rate and the ISI in multipath in standard techniques like QAM are high which are reduced by implementing the OFDM technique. |
