Approximate computing in hardware is generally aimed at power or energy optimization as the primary target. We suggest that hardware approximate computing can be more benecial when area reduction is the primary target. Additionally, we advocate that the hardware approximation schemes which allow usage of high-level libraries for their sub-components can leverage the power oered by modern synthesis...
A robust matched filter based timing synchronization scheme for orthogonal frequency division multiplexing (OFDM) systems is presented to achieve improved performance. Training symbol based timing synchronization often exhibits large estimation variance, resulting in performance degradation. The proposed method performs training symbol based timing synchronization at the receiver using matched filter,...
