The reference model selected by MPEG for the forthcoming unified speech and audio codec (USAC) switches between a non-LPC based coding mode (based on AAC) operating in the transform domain and an LPC-based coding mode (derived from AMR-WB+) operating either in the time domain (ACELP) or in the frequency domain (wLPT). Seamlessly switching between these different coding modes required the design...

Golomb coding is a special case of Huffman coding that is optimal for the data with geometric progression distribution probability. In this paper, we will generalize the Golomb coding by joint probability. In image progression, there are many conditions that the probability of a data not only has geometric distribution probability but also depends on another data. (For example, the difference b...

Stefan H. Müller–Weinfurtner Wireless Systems Research Dept., AT&T Labs – Research, 200 Laurel Avenue South, Middletown, NJ 07748, USA Abstract—The multiple antenna channel coding problem in Orthogonal Frequency–Division Multiplexing is reconsidered, because with frequency interleaving the effective channel characteristic across tones is rather fast fading and does not comply with the quasi–sta...
