What is multi-rate digital signal processing?
Multi-rate signal processing, an important part of the design of a digital frequency converter, is realized mainly based on interpolation and decimation, which match the sampling rate between the baseband and high-frequency processing side, especially in down conversion.
Why are multirate signal processing so important?
Multi-rate processing finds use in signal processing systems where various sub-systems with differing sample or clock rates need to be interfaced together. At other times multi-rate processing is used to reduce computational overhead of a system.
What are the advantages of multirate systems?
Potential advantages of multirate signal processing are reduced computational work load, lower filter order, lower coefficient sensitivity and noise, and less stringent memory requirements. Disadvantages are more complex design, aliasing and imaging errors, and a more complex algorithm.
What are the applications of multirate system?
Channel Equalization in Filter Bank Based Multicarrier Modulation for Wireless Communications.
