Path search for CDMA implementation |
摘要 |
A digital signal processor performs path search calculations for a Rake receiver. Despread operations are performed for multiple relative delays over a subcorrelation length by shifting either received chips or code chips for each relative delay. The result of a despread operation for a relative delay is added to the result of previous despread operations of the same delay performed on prior subcorrelation lengths. These calculations are performed in response to a single instruction. By issuing multiple instructions, path search calculations are performed for the entire correlation length.
