Abstract
Provided are a method and vector computing unit for implementing de-scrambling and de-spreading, and a computer storage medium. The method includes that: an operation of complex multiplication on baseband data and corresponding de-scrambling and de-spreading codes is performed by adopting data transformation and addition, and data obtained by the complex multiplication is stored into a vector register file; a row of data obtained by the complex multiplication is read from the vector register file, every two adjacent pieces of data in the row of data are accumulated to obtain a half row of data, a ¼ row of data, and finally one piece of accumulated data; and the accumulation processing is continued on other rows of data to implement accumulation of each row of data obtained by the complex multiplication in the vector register file.
