Abstract :
An improved pre-sorting and reordering algorithm is proposed for enhancing the quality of transmitting real-time MPEG-4 AAC (advanced audio coding) audio over EGPRS (Enhanced General Packet Radio Service). Compared with the standard Huffman codeword reordering (HCR) algorithm, lower implementation complexity and much better audio signal reconstruction quality may be achieved with the proposed scheme.
