ABSTRACT: The system
performance has been analyzed for π/4 DQPSK mapping scheme, which is differential
in nature and hence adding additional advantage. Performance evaluation with
random data as well as some images has been taken. Channel modeling has been
performed in multipath fading environment. For elaboration of the concept
mathematical modeling has been implemented using computer simulation. In this
paper, an attempt is made to know the capabilities of DHT-OFDM with non conventional
mapping technique π/4 DQPSK.
