Lesson 4 - Multi-Rate Systems
Creating Multi-Rate Systems
The following illustration shows a typical base-station receiver. The tower has multiple antennas to provide
sectored coverage of the area. The diagram shows that this results in two receiver channels. In each of these
channels, there is some form of complex mixing, resulting in real and imaginary channels.
Often DSP systems such as this will down sample the input signals prior to the digital filtering steps performed
during equalization and demodulation. Doing so can simplify the filter design and hardware significantly. These
systems are referred to as “multi-rate” systems
