Beam-space multiplexing has been demonstrated as a promising approach for transmitting multiple signals while using a single RF chain. This paper presents a novel beam-space antenna design that is very compact and integrated into a hypothetical portable pl ...
Email Print Request Permissions Save to Project Linear receivers are often used in multiple-antenna systems due to ease of implementation. However, traditional linear receivers such as the Decorrelator and the linear minimum-mean squared error (MMSE) recei ...
An approach for transmitting multiple signals using a single switched parasitic antenna (SPA) has been recently reported. The idea there is to map the signals to be transmitted onto a set of basis functions that serve as “virtual antennas” in the beamspace ...

A previous study of a novel technique to design a band-reject UWB monopole antenna by using patch loading is extended. Frequency-domain measurements have confirmed that the antenna designed using this technique rejects the interfering signal at the two int ...
A multi-input, multi-output antenna comprises an electrically conductive body, generally symmetrical about a plane of symmetry. An active port (Feed point) is located on the plane, a first parasitic port (1) is located on one side of the plane, and a secon ...
complexity of multiple antenna systems. In a traditional linear receiver architecture, the receive antennas are used to separate out the codewords sent by each transmit antenna, which can then be decoded individually. Although easy to implement, this appro ...

In this paper, we investigate the diversity-multiplexing tradeoff (DMT) of the multiple-antenna (MIMO) static half-duplex relay channel. A general expression is derived for the DMT upper bound, which can be achieved by a compress-and-forward protocol at th ...

The electric field enhancement associated with detailed structure within novel optical antenna nanostructures is modeled using the surface integral equation technique in the context of surface-enhanced Raman scattering (SERS). The antennae comprise random ...
This paper presents implementations of very wideband antennas with reconfigurable band-rejection filtering within the band. The base antenna topology used is a dipole slot bow-tie whose maximal dimension at the lowest matched frequency is only 0.2λ0. The a ...
The main purpose of the System Fidelity Factor (SFF) is to incorporate frequency and time domain characteristics of an antenna system into a comparison method for ultrawideband (UWB) antennas. The SFF is an interesting tool because both simulations and mea ...
