Prateema Ragpot, Tulsi Pawan Fowdur, Sunjiv K. M. Soyjaudah . Performance of a Two Level Unequal Error Protection Scheme for MP3 Transmission over LTE. Communications on Applied Electronics. 6, 10 ( Apr 2017), 35-41. DOI=10.5120/cae2017652575
Long-Term Evolution (LTE) is a wireless broadband communication technology which is highly used for the transmission of data and voice over the internet. However, due to noise and other channel deteriorations, the transfer of data and voice over LTE is very challenging. With the phenomenal increase of data and voice traffic, the management of Quality of Service (QoS) is a challenging problem. This paper presents an enhanced audio transmission scheme with two levels of Unequal Error Protection (UEP) for audio over LTE. The unequal importance of the bits generated by an MP3 codec as well as the varying importance of the bitstreams generated by a Turbo encoder is exploited and different level of protection are offered to them during LTE transmission. This is achieved by positioning the different bits in such a way so that the least important ones are given less protection than the more important bits. With 16-Quadrature Amplitude Modulation (QAM), the proposed two level UEP scheme provides an average gain of 22.36 dB in Segmented Signal to Noise Ratio (SSNR) over a conventional Equal Error Protection (EEP) one at a Turbo code rate of 1/2.
