This paper investigates the effects of moving speed on handover performances with measurement data from three scenarios, i.e., viaduct environment, cutting environment and urban area. To do so, we first extract some samples from measurement data. As the data neglected the effect of shadow fading and interchannel interference (ICI), we then add some values into the data, which are the shadowing generated...
In this paper, a low complexity algorithm is proposed for dual pseudorandom noise (PN) time domain synchronous OFDM (TDS-OFDM) systems, to simultaneously estimate the carrier frequency offset (CFO) and the sampling frequency offset (SFO). The second PN of every OFDM frame is used in the estimation. Firstly, SFO is estimated under maximum likelihood (ML) criterion. After that, a closed-form solution...
