JOINT 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 because ...

BALANCING OUTAGE PERFORMANCE OF PRIMARY USER AND SECONDARY USER BY RELAY-ASSISTED PRIMARY TRANSMISSION
In this paper, a cooperative transmission protocol for cognitive radio systems is proposed. In this protocol, the primary system comprises a transmitter (PT), a receiver (PR), and a decode-and-forward relay (Relay), while the secondary system comprises a transmitter (ST) and a receiver (SR). Both the ST and the Relay assist the transmissions of the primary users together. The outage probabilities ...

A REFINED AFFINE APPROXIMATION METHOD OF MULTIPLICATION FOR RANGE ANALYSIS IN WORD-LENGTH OPTIMIZATION
Affine arithmetic (AA) is widely used in range analysis in word-length optimization of hardware designs. To reduce the uncertainty in the AA and achieve efficient and accurate range analysis of multiplication, this paper presents a novel refined affine approximation method, Approximation Affine based on Space Extreme Estimation (AASEE). The affine form of multiplication is divided into two parts. ...

SINGLE-CHANNEL NOISE REDUCTION USING UNIFIED JOINT DIAGONALIZATION AND OPTIMAL FILTERING
In this paper, the important problem of single-channel noise reduction is treated from a new perspective. The problem is posed as a filtering problem based on joint diagonalization of the covariance matrices of the desired and noise signals. More specifically, the eigenvectors from the joint diagonalization corresponding to the least significant eigenvalues are used to form a filter, which effecti...

AN IMPROVED BLOCK DIAGONAL PRECODING SCHEME FOR MIMO MULTICAST CHANNEL WITH TWO USERS
Matrix theory plays an important role in precoding methodology for multiple input multiple output (MIMO) systems. In this paper, an improved block diagonal (BD) precoding scheme is proposed for a MIMO multicast channel with two users, where the unitary precoding matrix is constructed in a block-wise form by joint triangularization decomposition. In order to reduce large signal-to-noise ratios (SNR...
