Power Efficient Reconfigurable Fast Filter Bank for Multi-Standard Wireless Receivers
نویسنده
چکیده
This brief presents a reconfigurable fast filter bank (RFFB) with less gate counts for wireless communication applications such as spectrum sensing and channelization. This is designed with an improved modified frequency transformation-based variable digital filter (MFTVDF) at the first stage of the multistage implementation. The low-pass MFT-VDF offers unabridged control over the cutoff frequency on a wide frequency range thereby, improving the cutoff frequency range. The high gate counts are reduced by TBW of the filters. Keywords— Fast filter bank (FFB), reconfigurability, variable digital filter (VDF).

In a typical multi-standard wireless communication receiver, the channelizer must have the capability of extracting multiple channels (frequency bands) of distinct bandwidths corresponding to different communication standards. The channelizer operates at the highest sampling rate in the digital front end of receiver and hence power efficient low complex architecture is required for costeffectiv...

متن کاملA reconfigurable multi-standard channelizer using QMF trees for software radio receivers
The flexibility of a software-defined radio (SDR) depends on its capability to operate in multi-standard wireless communication environments. The most computationally intensive part of wideband receivers is the channelizer, which extracts multiple narrowband signals from adjacent frequency bands. In an SDR receiver, the compatibility of the channnelizer with different communication standards is...
متن کاملReconfigurable Filter Banks for Software Defined Radio Receivers – An Alternative Low Complexity Design to Conventional DFT Filter Banks
A new approach to implement computationally efficient reconfigurable filter banks for software defined radio receivers is presented in this paper. If the coefficients of a finite impulse response (FIR) filter are decimated by M, i.e., if every M-th coefficient of the filter is kept unchanged and remaining coefficients are replaced by zeros, a multi-band frequency response will be obtained. The ...
