5. Convolutional Codes for Wireless Packet Data Systems
Abstract : Automatic Repeat reQuest (ARQ) schemes can guarantee an almost error freereception strongly required in data communications. Hybrid type-II ARQschemes are supplied with channel coding to further improve the performance.In these schemes, error correction is performed adaptively which makesthem favorable for applications in time varying channels.
