Abstract
This article studies a vital issue in wireless communications, which is the transmission of audio signals over wireless networks. It presents a novel interleaver scheme for protection against error bursts and reduction the packet loss of the audio signals. The proposed technique in the article is the chaotic interleaver; it is based on chaotic Baker map. It is used as a randomizing data tool to improve the quality of the audio over the mobile communications channels. A comparison study between the proposed chaotic interleaving scheme and the traditional block and convolutional interleaving schemes for audio transmission over uncorrelated and correlated fading channels is presented. The simulation results show the superiority of the proposed chaotic interleaving scheme over the traditional schemes. The simulation results also reveal that the proposed chaotic interleaver improves the quality of the received audio signal. It improves the amount of the throughput over the wireless link through the packet loss reduction.

Summary
With increasing utilization of wireless devices, especially Bluetooth devices, there are two important factors for all wireless systems power efficiency and efficient throughput. Bluetooth is designed to transfer data using ACL packets and SCO packets for transferring audio streams [1,2]. The proposed technique improves the quality of the received audio signals and reduces the dropped packets over the bursty channel. The second audio file-2 has different properties as shown in the simulation assumption section. The second audio file-2 does not meet Bluetooth specification It is used with the long packets simulations. Different interleaving techniques are applied on the audio signal before transmission process. This is a realistic assumption to simulate the real Bluetooth systems’ operation [22] This assumption is employed to measure the number of corrupted packets, but the received packets are recollected after the decoding process for reconstruct the received audio signal. The simulation results have been acquired by the transmission of audio files over different SNR values
