Recent studies have shown that micro-RNAs (miRNAs) play a key role in inter-cell communication in humans. More importantly, irregular patterns over specific miRNAs have been linked to certain types of cancer and cardiac diseases. In this paper, we introduce a general framework to sense environmental miRNAs and detect certain irregular patterns. We use a sensor cell (i.e., biosensor) array comprising...
The application of LTE to the machine-type communications (MTC) poses some serious challenges due to the large performance mismatch between the regular LTE user equipment and the MTC device, caused mainly by the physical limitations of MTC devices. This paper addresses these limitations and their implications to the communication signal's link performance and the corresponding link budget. The focus...
We address the transceiver design problem for amplify-and-forward (AF) MIMO two-way relay systems with imperfect channel estimation. Since only estimated channel state information (CSI) is available, the self-interference (SI) cannot be completely canceled at destination nodes. With both channel estimation errors and residual self-interference considered, we propose two robust schemes to minimize...
In this letter, the limited feedback scheme in MIMO-Relay systems is considered. We propose a new strategy that optimizes the allocation of feedback bits between channel direction information (CDI) and phase information (PI) for multi-relay systems under the total number of feedback bits constraint. The proposed scheme eventually trades off some CDI bits for PI feedback to diminish the phase ambiguity...
