Multiuser Channel Estimation for Ultra-Wideband Systems Using up to the Second-Order Statistics
In a pulse-position modulation-based ultra-wideband (UWB) communication system, multiple access is enabled by assigning unique time-hopping sequences to different users. Each user’s data information is carried by positions of short pulses which are directly transmitted through an unknown and possibly dense multipath channel. Single-user channel estimation methods have been proposed by maximum l...
متن کاملchannel estimation for mimo-ofdm systems
تخمین دقیق مشخصات کانال در سیستم های مخابراتی یک امر مهم محسوب می گردد. این امر به ویژه در کانال های بیسیم با خاصیت فرکانس گزینی و زمان گزینی شدید، چالش بزرگی است. مقالات متعدد پر از روش های مبتکرانه ای برای طراحی و آنالیز الگوریتم های تخمین کانال است که بیشتر آنها از روش های خاصی استفاده می کنند که یا دارای عملکرد خوب با پیچیدگی محاسباتی بالا هستند و یا با عملکرد نه چندان خوب پیچیدگی پایینی...
Blind channel estimation using the second-order statistics: algorithms
Most second-order moment-based blind channel estimators belong to two categories: i) optimal correlation/spectral fitting techniques and ii) eigenstructure-based techniques. These two classes of algorithms have complementary advantages and disadvantages. In this paper, a new optimization criterion referred to as the joint optimization with subspace constraints (JOSC) is proposed to unify the tw...
متن کاملChannel estimation for ultra-wideband communications
This paper deals with channel estimation in ultra-wideband communications operating in a multipath environment and in the presence of multiaccess interference. The channel parameters are the attenuations and delays incurred by the signal echoes along the propagation paths. Time-hopping modulation with binary symbols is assumed. The estimation method is based on the maximum-likelihoodcriterion a...
متن کاملConsistent estimation of Rayleigh fading channel second order statistics in the context of the wideband CDMA mode of the UMTS
In this paper, we address the problem of estimating the second-order statistics of a frequency-selective Rayleigh channel in the context of the wideband CDMA mode of the UMTS. The data to be transmitted are sent over slots on which the channel is assumed to remain constant. Each slot contains a pilot symbol sequence from which it is possible to estimate the current value of the channel. The cov...
