Complexity Reduction of Blind Decoding Schemes Using CRC Splitting

Executive Summary

Blind decoding, used on control channels of some multi-user wireless access systems, is a technique for achieving adaptive modulation and coding. The idea is to adapt the modulation and coding scheme to the channel quality but instead of signaling the parameters used explicitly, the receiver blindly tries a number of fixed parameter combinations until a successful decoding attempt is detected, with the help of a cyclic redundancy check. In this paper, the authors suggest a new method for reducing the complexity and energy consumption associated with such blind decoding schemes.
