Abstract

The BER performance of any wireless communication system is the primary factor of consideration for the network under evaluation. Turbo-coded OFDM systems have always outperformed other communication standards in terms of delay of communication, overall system efficiency and flexibility. But the BER performance of turbo-coded OFDM systems has always been a challenge for network designers, due to the fact that turbo encoders vary largely in terms of their primary specifications like code length and code rate among other network parameters. In this paper, we propose an artificial intelligence (AI) layer for turbo-coded OFDM systems, which improves the BER performance of the system, and also reduces the delay of communication by intelligent selection of network specifications. Our AI is trained for minimizing the BER of the communication network, but it can be used to target one or many parameters as per the requirements of the network designer.
