Frequency-offset estimation for HIPERLAN
Frequency-offset correction is considered for a HIPERLAN (HIgh-PErformance Radio LAN) system over the indoor radio channel. Since the multipath channel response is not known a priori, a viable frequency-offset estimator should not depend on such knowledge. Such an estimator, using a single sample per symbol, is derived for HIPERLAN. The estimator is shown to approach the Cramer–Rao bound for fr...
متن کاملFrequency offset estimation for GSM and EDGE
A low complexity method for estimating the frequency offset in global system mobile(GSM) and enhanced data rates for GSM evolution (EDGE) is proposed. The method isbased on minimising a suitable least squares (LS) metric utilising both the pilot (training)and tail symbols available in GSM and EDGE. It is shown that the tail symbols areimportant in estimating frequency offset eve...
متن کاملFrequency Offset Estimation for IFDMA Uplink Systems
This paper proposes two frequency offset estimation algorithms for the uplink of an Interleaved Frequency-Division Multiple-Access (IFDMA) system. One algorithm performs estimation in the frequency domain and the other in the time domain. Both algorithms are based on the maximum likelihood estimation (MLE) principle and use knowledge about pilot symbols. IFDMA utilizes a block-interleaved frequ...
متن کاملCarrier Frequency Offset Estimation for Orthogonal Frequency Division Multiplexing Systems
Carrier Frequency Offset Estimation for Orthogonal FrequencyDivision Multiplexing Systems Xiang Nian Zeng, Ph.D. Concordia University, 2008 Orthogonal frequency division multiplexing (OFDM) is an attractive modulation scheme used in wideband communications because it essentially transforms the frequency selective channel into a flat fading channel. Furthermore, the combination of multiple-input...
متن کاملBER Estimation for HiperLAN/2
This paper presents a method to estimate the bit error rate (BER) of the wireless channel based on statistical analysis of the soft output of the receiver only. In HiperLAN/2 several modulation schemes can be used. The system should select the most suitable modulation scheme dependent on the quality of the wireless link and the Quality of Service requirements of the user. Our BER estimation met...
