    • Channelization of wideband signal based on critical sampling polyphase filter banks

    • “In the fields of communication and radio astronomy, experts have analyzed the impact of different window functions on the performance of FIR digital filters through simulation to address the issue of broadband signal sub-band partitioning. Based on the Hamming window FIR digital filter, a critical sampling multiphase filter bank has been designed and implemented, providing a solution to the problems of spectrum leakage and sub-band aliasing.”
