Implementing Carrier Phase Recovery Loop Using Vivado HLS Application Note (XAPP1173) - This application note describes the implementation of a carrier phase recovery loop algorithm for a single carrier QAM demodulator using Vivado High-Level Synthesis (HLS). The algorithm, described in C/C++, is converted to synthesizable RTL by Vivado HLS, exported to System Generator for DSP for verification, and then implemented using the Vivado Design Suite.
