Covert Communication with Channel-State Information at the Transmitter
We consider the problem of covert communication over a state-dependent channel, where the transmitter has causal or noncausal knowledge of the channel states. Here, “covert” means that a warden on the channel should observe similar statistics when the transmitter is sending a message and when it is not. When a sufficiently long secret key is shared between the transmitter and the receiver, we d...
متن کاملAdaptive MIMO Systems with Channel State Information at Transmitter
This dissertation presents adaptation techniques that can achieve high spectral efficiency for single user multiple-input multiple-output (MIMO) systems. Two types of adaptation techniques, adaptive modulation and adaptive power allocation, are employed to adapt the rate and the transmit power to fading channels. We start by investigating the adaptive modulation subject to a certain bit-error-r...
متن کاملCommunication over Channels with Causal Side Information at the Transmitter
This work deals with communication over the AWGN channel with additive discrete interference, where the sequence of interference symbols is known causally at the transmitter. We use Shannon’s treatment for channels with side information at the transmitter as a framework to derive “optimal precoding” and “channel code design criterion” for the channel with known interference at the transmitter. ...
متن کاملAdaptation in Multiple Input Multiple Output Systems with Channel State Information at Transmitter
The thesis comprises two parts: the rst part presents channel-adaptive techniques to achieve high spectral e ciency in a single user multiple-input multiple-output (MIMO) system; the second part exhibits a programmable and recon gurable software-de ned-radio workbench (SDR-WB) in the Matlab/Octave environment that accommodates a variety of wireless applications. In an attempt to achieve high sp...
متن کاملwith Side Information at the Transmitter
The basic problem that we will be looking at can be described as follows and is illustrated in Figure 1. The overall objective (as usual) is to reliably communicate a message m ∈ {1, . . . , 2nR} from the encoder to the decoder using the channel n times. The largest rate R for which this is possible is called the capacity of the channel. The channel that we can use is described by a conditional...
