A Fractionally Asymmetric Sub–Nyquist Baseband Receiver Design and Implementation for Phase Modulated Signals

Sub–Nyquist sampling is a technique which has various applications in signal processing and communication technologies. Memory relaxation, peripherals operating at relatively lower speeds, consequently low–power consumption designs are prominent motivations sub–Nyquist receiver studies. Although these seem to be attractive, instability information loss major drawbacks of approaches comparison with Nyquist–Shannon applications. Nevertheless, sub-Nyquist receivers could still provide several ways recovering some extent case they fortified appropriate interpolation mechanisms. Hence, this study proposes fractionally asymmetric baseband design for phase modulation (PM) reception. The proposed method takes advantage statistical behaviors the received passing through physical propagation medium adopts an autoregressive process recover required. implemented on software-defined radio (SDR) platform near real–time tested real–world environment. Results discussions provided along future directions.
