摘要： The present disclosure discloses a method for assigning signature sequences for E-HICH channel which may avoid the unbalanced situation brought about by the codeword assignment, wherein the use of UE signature sequences on E-HICH channel is equalized, so as to drive the average detection performance toward equity for different UEs to detect their respective signature sequences on E-HICH channel, and to reduce the average false detection rate for the respective UE on the feedback information transmitted thereto. The method comprises: firstly, assigning a E-HICH logical signature sequence index r for each UE; then, converting the logical signature sequence index r into a physical signature sequence index r′ varying with time by using a random permutation function; and after that, assigning a signature sequence corresponding to the physical signature sequence index r′ to the respective UE.

摘要： A method for arithmetic expression optimization includes receiving an operator and at least one operand of a first instruction defined for a first processor having a first base. The method also includes converting the first instruction to a second instruction optimized for a second processor having a second base smaller than the first base when overflow is impossible based at least in part on the operator and the relationship between the operand type and the second base. The method also includes converting instructions in an instruction chain to a wider base larger than the second base and smaller or equal to the first base when the at least one operand carries potential overflow beyond the second base and when the operator is sensitive to overflow. The chain is bounded by the second instruction and a third instruction that has been previously optimized and is the source of the potential overflow.
