In addition to the performance advantages of new transmission techniques, implementation aspects are of increasing interest. Accordingly, modern receiver architectures use non-synchronized sampling. Timing adjustment is completely performed in the digital domain. In this contribution ,we present a new digital approach for sampling frequency synchronization, based on non-synchronized sampling in OFDM systems. Compared to known feedback techniques, an advantageous method, based on NDA feedforward processing, is applied. Because this is a novel technique, particular emphasis is placed on timing error detection. This calculates the sampling frequency offset directly from the incoming time domain samples. Based on this information, a control parameter for the correction by interpolation can be derived. The solution presented offers many advantages and meets the requirements of modern receiver technology. It can be used for WLAN systems based on OFDM modulation.
