Continuously Variable Bandwidth Filters for Low Complexity Reconfigurable Uniform and Non- Uniform SDR Channelizers

In this paper, a hardware efficient low complexity continuously variable band width filter is proposed to be applied in software defined radio channelizers. Uniform and non-uniform reconfigurable filter banks can be obtained using the proposed structure. The proposed structure is compared with the existing structures with design examples. It is observed that the proposed structure has a much lower complexity than the existing methods.
