Novel ARQ techniques for land mobile satellite systems
Abstract
Classical ARQ (Automatic Repeat Request) techniques based on pure error detection are well suited for high quality channels being only occasionally affected by errors. For many channels with higher noise level or time varying statistics, however, other concepts are required, in which both error correction and detection are applied; these are called 'hybrid ARQ' in literature. For land mobile channels even hybrid ARQ concepts are not necessarily optimum. Thus in this paper novel ARQ techniques, particularly suited for land mobile applications, are introduced. A comparative analysis of these new concepts is presented.
