Sparse Multipath Wireless Channels: Modeling and Implications
Most existing works in wireless communications assume a rich multipath environment. In particular, the intense research on multi-antenna (MIMO) systems in the last decade was pioneered by results based on an i.i.d. channel model representing a rich multipath environment. However, there is growing experimental evidence that physical wireless channels exhibit a sparse multipath structure, even at...
متن کاملFast Sparse Multipath Channel Estimation with Smooth L0 Algorithm for Broadband Wireless Communication Systems
Broadband wireless channels are often time dispersive and become strongly frequency selective in delay spread domain. Commonly, these channels are composed of a few dominant coefficients and a large part of coefficients are approximately zero or under noise floor. To exploit sparsity of multi-path channels (MPCs), there are various methods have been proposed. They are, namely, greedy algorithms...
متن کاملPartially Linear Bayesian Estimation with Application to Sparse Approximations
We address the problem of estimating a random vector X from two sets of measurements Y and Z , such that the estimator is linear in Y . We show that the partially linear minimum mean squared error (PLMMSE) estimator does not require knowing the joint distribution of X and Y in full, but rather only its second-order moments. This renders it of potential interest in various applications. We furth...
متن کاملSparse Multipath Channel Estimation Using Compressive Sampling Matching Pursuit Algorithm
Wideband wireless channel is a time dispersive channel and becomes strongly frequency-selective. However, in most cases, the channel is composed of a few dominant taps and a large part of taps is approximately zero or zero. To exploit the sparsity of multi-path channel (MPC), two methods have been proposed. They are, namely, greedy algorithm and convex program. Greedy algorithm is easy to be im...
متن کاملAn Application of SAGE Algorithm for UWB Propagation Channel Estimation
In this paper, a new Ultra Wideband (UWB) channel estimation algorithm, UWB-SAGE (Space Alternating Generalized Expectation Maximization) is proposed. This algorithm is an extension of conventional SAGE algorithm which is often adopted for wideband channel estimation. The algorithm divides the measured data into individual ray paths and estimates the directions of arrival, propagation time, and...
