Abstract:
Frequency offset (FO) estimation and compensation is critical to the performance of orthogonal frequency division multiple access (OFDMA) systems. In uplink single carrier SC-OFDMA systems, such as long term evolution (LTE), traditional correlation-based time-domain FO estimation techniques are not valid due to the presence of multi-users. Thus, frequency-domain techniques are mostly used. In case of frequency hopping (FH) in uplink LTE, correlation-based frequency-domain techniques cannot be used and other alternative techniques give modest results. In this paper, we propose a novel timedomain FO estimation technique and show that it results in superior performance in case of FH.
