Abstract
The present invention relates to an interpolation FIR (finite impulse response) filter having multiple data rates in a mobile communication system, and a method of filtering data using the same. In the method of filtering data using the interpolation FIR filter, a first filter uses an FIR low pass filter that restricts a band to satisfy a bandwidth corresponding to a data spectrum mask required in the mobile communication system. The other filters use interpolation FIR halfband filters that are implemented by a small number of taps. Accordingly, the interpolation FIR filter having multiple data rates can be easily implemented, and can be easily applied to the mobile communication system that transmits and receives data having various data rates.
