摘要：
The timing tracking of millimeter-wave wireless communications is very challenging since the analog to digital converters (ADCs) cannot provide high oversampling on the received signals and the multi-path channel causes tracking problems. Two timing tracking schemes based on twice over-sampled data and the waveform of the correlation values using Farrow interpolation are described in this paper for multi-path channels. The first scheme compensates for the timing error before channel equalization while the other compensates afterwards. Simulations show that with a timing error of 20×10-6 and a bit error rate (BER) of 10-5, the difference in the signal-to-noise ratios (SNRs) between these two systems and a system with no timing error is about 2.5 dB less than with the Rummler channel. Thus, both schemes provide good timing tracking for multi-path channels. © 2017, Tsinghua University Press. All right reserved.
