Surprisingly, the effect of the local oscillator ...
Such packet loss will be detrimental not only to the function of multi-channel acoustic signal processing over the network, but may deteriorate already the necessary estimation of sampling rate offset (SRO) between ad-hoc sensor nodes from incomplete waveforms. To study this aspect, the paper ...

Sampling frequency offset (SFO)Real-time signal processingSampling frequency offset (SFO) will result in phase rotation, inter-channel interference, and inter-symbol interference, which can seriously degrade the transmission performance of the asynchronous direct-detection optical OFDM (DDO-OFDM). In ...
Such high sampling rates can be achieved with time-interleaved analog-to-digital converters (TI-ADCs). Even though TI-ADCs are faster, the sampling time offset is a setback. The sampling time offsets present in ADCs generate nonuniform samples. In the reconstruction process, these nonuniform ...

Compensating for local oscillator and sampling frequency offsets in an OFDM receiverA partial Fourier Transform is performed, using Goertzel's algorithm, to calculate two frequency bins. A phase variation is calculated for each bin, the phase variation preferably representing the phase difference ...
