Problems solved by technology

The advantage of the parallel scheme is that 9 sample data are input in parallel, and 8 sample data are output in parallel after interpolation. The throughput is large and the control logic is simple; the disadvantage is that 16 multipliers and 14 adders are required, and the logic resource consumption is large.

Abstract

The apparatus comprises: a control unit used for controlling the interpolation processing unit and generating the sample data, interpolation factor and control signal required by the interpolation processing unit; and an interpolation processing unit used for, under the control of the control unit, using the sample data, interpolation factor and control signal to make the multiply and summation calculation for the sample data, and transmitting the processed sample data to the control unit in order to output it.

Description

technical field [0001] The present invention relates to the communication field, and more particularly relates to an interpolator serial processing device and method. Background technique [0002] The interpolation technology is a commonly used code processing technology in a Wideband Code Division Multiple Access (WCDMA) system. In the WCDMA system, different interpolation algorithms can be used to complete interpolation according to performance requirements. The 8TAP interpolation algorithm that the present invention realizes is as follows: [0003] [0004] [0005] [0006] [0007] rounded down, [0008] Among them, z(k) is the interpolated data, y(i) is the original sample data, phase k (i) is the interpolation coefficient (hereinafter abbreviated as p k (i)). [0009] The interpolation process is to calculate the output 8-sample data through the input historical 9-sample data. Among them, the original 9-sample data y(0), y(1), y(2), y(3), y(4), y...
