Power constrained channel optimized vector quantizers used for bandwidth expansion
KTH, School of Electrical Engineering (EES), Communication Theory.
2007 (English)In: Proceedings of 4th IEEE Internatilonal Symposium on Wireless Communication Systems 2007, ISWCS, New York: IEEE , 2007, 667-671 p.Conference paper, Published paper (Refereed)
Abstract [en]

This paper deals with algorithms for determining well performing bandwidth expanding joint source-channel coding (JSCC) systems. The JSCC systems are realized as direct source-channel mappings. The algorithms presented are "Power Constrained Channel Optimized Vector Quantizers" (PCCOVQ). The PCCOVQ algorithm is a modified generalized Lloyd algorithm. Theory on PCCOVQ is presented, with the emphasis on bandwidth expansion. Examples and results concerning bandwidth expansion by a factor of 2 and 3 are given.
