Abstract
A method and apparatus in a radio telecommunications system for converting data from a first sample rate to a second sample rate such that the first and second sample rates are preferably within 10% of each other are disclosed. An input buffer receives a plurality of data groupings at a first sample rate. A spline filter utilizes the input data along with a phase difference between input and output data to calculate a third order spline function and an output time for the input data. This information is used to convert the input data at the first sample rate to output data at a second sample rate. The output data is buffered within an output buffer until transmitted to an associated base band unit.
