Asymmetric Channel Cooperative Compression

Abstract
An asymmetric channel environment is considered and the slow uplink direction is speeded-up by means of a new compression scheme, based on a dictionary transmitted on the downlink channel. The performance of this cooperative scheme approaches those of perfect knowledge of dictionary and it improves as much as the download over upload ratio improves. The letter makes an investigation on this cooperative structure, on the their performance and on the dictionary compositions.File in questo prodotto:
