In this research, We interest to studying two methods of ways to increase the reliability of wireless communication, namely: hybrid retransmission protocols (HARQ Protocols) and adaptive coding data (Adaptive Coding), in order for the wireless commun
ication system between two points: the first is fixed and represents the control and leadership station .The second represents a body moving and it is controlled from the command station , it performs various measurements and sent it to the command station.
This thesis mainly discusses how to embed and transmit information in audio by making use of acoustic OFDM. Based on the theoretical systematic structure, it also modeled and simulated the system under different communication channels such as AWGN and Rayleigh fading, using the MATLAB software.
