Orthogonal frequency division multiplexing (OFDM) is a special case of multi-carrier
transmission and it can accommodate high data rate requirement of multimedia based …

In this work, we consider the two-way relay network (TWRN) where two terminals exchange
their information through a relay node in a bi-directional manner and study the training …

In this paper, we study the problem of estimating correlated multiple-input multiple-output
(MIMO) channels in the presence of colored interference. The linear minimum mean square …

We study the performance of joint signature-receiver optimization for direct-sequence code-
division multiple access (DS-CDMA) with limited feedback. The receiver for a particular user …

In this paper, we study the channel estimation and the optimal training design for relay
networks that operate under the decode-and-forward (DF) strategy with the knowledge of the …

In multiple-input multiple-output (MIMO) systems, power constraints are critically important
for transceiver designs. The most popular and widely used power constraint is sum power …

This paper proposes a training-based channel estimation scheme for achieving quality-of-
service discrimination between legitimate and unauthorized receivers in wireless multiple …

In this paper, optimal training sequence design for multiple-input multiple-output (MIMO)
intersymbol interference channels is addressed, and several novel low-complexity channel …

When the second-order statistics of channel and noise, such as their covariance matrices,
are not exactly known, the acquisition of accurate channel state information (CSI) for a …

We consider the problem of downlink training sequence design for frequency-division-
duplex multiuser massive multiple-input multiple-output systems in the general case where …
