A robust sparse least-mean mixture-norm (LMMN) algorithm is proposed, and its performance is appraised in the context of estimating a broadband multi-path wireless channel. The proposed algorithm is implemented via integrating a correntropy-induced metric... see more

A group-constrained maximum correntropy criterion (GC-MCC) algorithm is proposed on the basis of the compressive sensing (CS) concept and zero attracting (ZA) techniques and its estimating behavior is verified over sparse multi-path channels. The proposed... see more

Context. Traditionally a large number of pilot carriers are utilized to acquire channel state information in OFDM based systems.A larger number of pilot carriers gives better channel state estimation but leads to lower spectrum efficiency of the system.Ob... see more

In this paper, the optimality of Compressive Sensing based Least Square (LS-CS) and Compressive Sensing based Minimum Mean Square (MMSE-CS) channel estimation algorithms in Multi Input Multi Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) ... see more

To make full use of space multiplexing gains for the multi-user massive multiple-input multiple-output, accurate channel state information at the transmitter (CSIT) is required. However, the large number of users and antennas make CSIT a higher-order data... see more

Based on convex programming for optimization, a closed-from solution of superimposed (SP) training on linearly precoded data for jointly optimal channel estimation and symbol detection is proposed in this paper for MIMO-OFDM systems. The newly designed me... see more

Objective. Comparative estimation of the pain syndrome in patients with concomitant pathology of anal channel and rectum after performance of combined operations, using modern high-frequency electro-surgical and radio-surgical apparatuses, as well as conv... see more

For the previous generation, the typical housing tenure pathway in Australia was more clearly defined, with young adults leaving the family home to marry and experience the birth of the first child while residing in a rental home, before entry into home o... see more
