Hey everyone,

I’ve designed a reconfigurable uniform polyphase channelizer optimized for FPGAs, targeting two major pain points in conventional implementations: limited configurability and excessive hardware resource overhead.

Compared with classic polyphase channelizer architectures, this design supports one-time hardware instantiation with runtime reconfiguration, fully pipelined dataflow, and single-cycle throughput.

Here are the core technical capabilities:

1. The hardware is sized for a maximum channel count C and subfilter tap length K. After deployment, it can dynamically work with any channel count c that is a power-of-two divisor of C.
2. Under any selected channel count c, the design supports arbitrary decimation factors ranging from 1 up to c.
3. It accepts arbitrary filter coefficient sets with total tap lengths less than \(c \times K\).

In terms of FPGA resource consumption, the overhead is nearly identical to a standalone decimation filter of length K paired with a serial C-point IFFT block.

I’ve conducted a thorough literature and patent search, and I cannot find any existing published work or granted patents that deliver this full set of flexible reconfiguration capabilities.

State-of-the-art polyphase channelizer implementations only optimize resource usage or throughput for fixed, narrow application scenarios. Most existing designs are constrained by serpentine shift registers and circular output shifting logic, which rules out flexible runtime reconfiguration.

Many fixed-function channelizers achieve higher raw throughput, but that performance comes at the cost of rigid hardware partitioning and locked parameter modes. I believe further speed optimizations are still possible within my flexible architecture without sacrificing its reconfigurability.

I’m reaching out to ask for industry/research perspective: does this reconfigurable polyphase channelizer hardware architecture carry meaningful commercial or IP licensing value?

Thanks a lot for any insights!
