Journal ArticleDOI
On the distribution of SINR for the MMSE MIMO receiver and performance analysis
TL;DR: A Gamma distribution and a generalized Gamma distribution are proposed as approximations to the finite sample distribution of T and simulations suggest that these approximate distributions can be used to estimate accurately the probability of errors even for very small dimensions.
Journal ArticleDOI
Finite-SNR Diversity–Multiplexing Tradeoff for Correlated Rayleigh and Rician MIMO Channels
TL;DR: A nonasymptotic framework for the diversity-multiplexing tradeoff of a multiple-input-multiple-output (MIMO) wireless system at finite signal-to-noise ratios (SNRs) is presented, which is useful in MIMO system design for realistic SNRs and propagation environments.
Journal ArticleDOI
Spatial multiplexing with transmit antenna and constellation selection for correlated MIMO fading channels
TL;DR: Compared with a system using all available antennas, performance results show significant gains using a subset of transmit antennas, even for independent fading channels, while a lower bound on the maximum outage data rate is derived.
Proceedings ArticleDOI
Wireless patch sensor for remote monitoring of heart rate, respiration, activity, and falls
TL;DR: In this paper, a wireless Bluetooth Low Energy (BLE) patch sensor consisting of two electrocardiography (ECG) electrodes, a microcontroller, a tri-axial accelerometer, and a BLE transceiver was evaluated on a total of 25 adults who performed breathing exercises, activities of daily living (ADLs), various stretches, stationary cycling, walking/running, and simulated falls.
Proceedings ArticleDOI
Individual Outage Rate Regions for Fading Multiple Access Channels
TL;DR: In this paper, outage regions are computed for the quasi-static fading multiple access channel (MAC) with constraints on the individual user outage probabilities and no channel state information at the transmitters (CSIT).
