This study presents an oversampling-based low-latency, high-resolution and low-cost timing synchronisation technique for digital receivers. Traditional timing synchronisation employs matched filter to estimate the signal coarse time of arrival. Here, latency increases through oversampling and resolution improves via higher bandwidth. The proposed method uses single bit quantisation to employ XNOR blocks instead of multiplier and accumulator blocks in the traditional method. This substantially decreases complexity incorporating less field-programmable gate array (FPGA) surface area.
