AI based digital companding scheme for Software Defined Radio

Data rate is important factor in telecommunication, it is directly proportional to the cost of transmitting the signal. Saving bits is the same as saving money. In this paper we propose new digital companding scheme based on Artificial Intelligence for Software Defined Radio applications, depending on the data to be transmitted AI (Artificial Intelligent) block compresses and expands the signal, 8 to 4 bit compression is proposed(16∶1 compression). The proposed scheme was simulated in Matlab7.4 and it was shown that the proposed companding scheme effective with low compression error.
