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 is the significance of multirate 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.
What are the applications of multirate system?
Channel Equalization in Filter Bank Based Multicarrier Modulation for Wireless Communications.
How does upsampling work?
Upsampling is the process of inserting zero-valued samples between original samples to increase the sampling rate. (This is sometimes called “zero-stuffing”.) This kind of upsampling adds undesired spectral images to the original signal, which are centered on multiples of the original sampling rate.
