Blind channel and carrier frequency offset estimation using periodic modulation precoders
Recent results have shown that blind channel estimators, which are resilient to the location of channel zeros, color of additive stationary noise, and channel order overestimation errors, can be developed for communication systems equipped with transmitter-induced cyclostationarity precoders. The present paper extends these blind estimation approaches to the more general problem of estimating t...
متن کاملJoint frequency offset, time offset, and channel estimation for OFDM/OQAM systems
Among the multicarrier modulation techniques considered as an alternative to orthogonal frequency division multiplexing (OFDM) for future wireless networks, a derivative of OFDM based on offset quadrature amplitude modulation (OFDM/OQAM) has received considerable attention. In this paper, we propose an improved joint estimation method for carrier frequency offset, sampling time offset, and chan...
متن کاملNon-data aided feedforward estimation of PSK-modulated carrier frequency offset - Communications, 2002. ICC 2002. IEEE International Conference on
This paper examines the asymptotic (large sample) performance of a family of non-data aided feedforward (NDA FF) nonlinear least-squares (NLS) type carrier frequency estimators for burst-mode phase shift keying (PSK) modulations transmitted through AWGN and flat Ricean-fading channels. The asymptotic performance of these estimators is established in closed-form expression and compared with the ...
متن کاملAnalysis of Reduction in Complexity of Multiple input- Multiple output-orthogonal frequency Division Multiplexing Systems with carrier frequency offset estimation and correction
Orthogonal Frequency Division Multiplexing (OFDM) is a promising research area in Wireless Communication for high data rates. The Multiple Input-Multiple Output (MIMO) technology when incorporated with the OFDM system promise a significant boost in the performance. But, the MIMOOFDM systems are very sensitive to Carrier Frequency Offset (CFO) as it deteriorates the system performance with the r...
متن کاملPerformance of non-data aided carrier offset estimation for non-circular transmissions through frequency-selective channels
We consider blind estimation of the carrier frequency o set of a linearly modulated non-circular transmission through an unknown frequency selective channel. A frequency estimator is developed based on the unique conjugate cyclic frequency of the received signal that equals twice the frequency o set. We establish consistency and asymptotic normality of the frequency estimator, and calculate its...
