This paper proposes a simple outlier data rejection algorithm for a received signal strength indicator (RSSI)-based maximum likelihood (ML) location estimation in wireless sensor networks. The RSSI-based ML location method usually requires a pre-determined statistical model on the variation of RSSI in a sensing area. However, when estimating the location of a target, due to several reasons, we often...
This paper describes a real-time performance evaluation of a receive antenna selection method for a spatial multiplexing multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) system in a real environment. In this real-time performance evaluation, we employed a receive antenna selection method to select a suitable set of polarization antennas at the receiver side of...
Receive antenna selection diverrsity in MIMO-OFDM transmission is attractive because it can achieve better BER performance due to higher diversity gain obtained, keeping the cost and energy consumption low. However, how to select a suitable set of receive antenna elements is a key issue, with low computational and hardware complexity. In this paper, we propose an receive antenna directivity diversity...
