The implementation of accurate solutions to synchronize the transceiver’s clocks in real-time operations plays a major role in the current development of communication systems. Considering the orthogonal frequency division multiplexing (OFDM)-based systems, adopted by the deployment of fifth-generation (5G), industrial networks, and the wireless local area network (WLAN) standard, several reported solutions focus on field-programmable gate array (FPGA) designs for the clock synchronization in real-time operations. However, reported solutions to describe with minor details the impact of the introduced quantization noise error (QNE) based on the implemented bit-width. Their study will provide insights to implement digital solutions of reduced complexity. The current article provides theoretical expressions to characterize accuracy and precision when synchronizing the transmitter’s clock. The presented analysis is intended to support designers to evaluate the clock synchronization design considering the bit-width to implement the given system.
