An Exact Blind Channel Estimator and Its Extensions to Additive Noise Channels
نویسندگان
چکیده
Recent work on fractionally spaced blind equalizers have shown that it is possible to exactly identify the channel and its input sequence from the noise–free channel outputs [1–3]. However, the obtained results are based on a set of over–restrictive constraints on the channel. We have shown that the exact identification can be achieved in a much broader class of channels [4]. In this paper, we present performance results of the exact channel estimator in the presence of noise.

Capacity Bounds and High-SNR Capacity of the Additive Exponential Noise Channel With Additive Exponential Interference
Communication in the presence of a priori known interference at the encoder has gained great interest because of its many practical applications. In this paper, additive exponential noise channel with additive exponential interference (AENC-AEI) known non-causally at the transmitter is introduced as a new variant of such communication scenarios. First, it is shown that the additive Gaussian ch...
متن کاملOn optimum parameter modulation-estimation from a large deviations perspective
We consider the problem of jointly optimum modulation and estimation of a real– valued random parameter, conveyed over an additive white Gaussian noise (AWGN) channel, where the performance metric is the large deviations behavior of the estimator, namely, the exponential decay rate (as a function of the observation time) of the probability that the estimation error would exceed a certain thresh...
متن کاملJoint maximum likelihood time-delay estimation for LTE positioning in multipath channels
This paper presents a joint time-delay and channel estimator to assess the achievable positioning performance of the Long Term Evolution (LTE) system in multipath channels. LTE is a promising technology for localization in urban and indoor scenarios, but its performance is degraded due to the effect of multipath. In those challenging environments, LTE pilot signals are of special interest becau...
متن کاملA new approach based on "soft statistics" to the nonlinear blind-deconvolution of unknown data channels
In this paper, we present a new nonlinear receiver for the blind deconvolution of intersymbol interference (ISI) impaired data. The proposed receiver achieves fast identification of an unknown transmission channel using only one channel estimator and requiring the computation of only the second-order conditional statistics of the baud-rate sampled received signal and the knowledge of the transm...
متن کاملModulation-index Estimaton in a Combined Cpm/ofdm Receiver
In this paper we develop a blind modulation-index estimator for a combined CPM/OFDM Receiver. The performance of the estimator in an AWGN channel is assessed by simulation and analysis and its suitability for our receiver is established.
