Modulation plays an important role in transmission of single from transmitter to receiver in all communication systems. But it is vital in wireless communication and a lot of communication features including (data rate, error rate, symbol rate, bandwidth etc) depends upon it. In NS2 wireless network simulation BPSK is used for digital encoding and modulation of data [1,2]. The BPSK method is us...

Several algorithms have been proposed to avoid the error floor region, such as concatenation codes that requires high computational demands in addition complexity. This paper proposes a technique based on using cascaded BCH and convolutional leads better correction performance. Moreover, an adaptive method sensing channel's noise determine number of parity bits will be added used reduces consum...
