Efficient Multi-Standard Software Defined Radio receivers implementation using Frequency response masking
2014
The compatibility of the filter bank with different communication standards requires dynamic reconfigurability. The polyphase channelizer has the advantage that the channel filter can be adjusted to better approximate the ideal magnitude response.Hanning Window functions can also be used to improve the side lobe response without any of the performance penalties associated with the FFT channelizer. The proposed FB offers reconfigurability at the architectural level and at the channel filter level and is capable of extracting channels of nonuniform bandwidths corresponding to multiple wireless communication standard from the digitized wideband input signal.
