The aim of this paper is to investigate receiver techniques for maximum likelihood (ML) joint channel/data estimation in flat fading multiple-input multiple-output (MIMO) channels, that are both (i) data efficient and (ii) computationally attractive. The performance of iterative least squares (LS) for channel estimation combined with sphere decoding (SD) for data detection is examined for block fading...
This paper presents a method to mitigate the interferences against pseudolite-type and continuous-wave interferences in a global navigation satellite system (GNSS) environment. Ground-based pseudolites can transmit GPS-liked signals and augment GNSS constellations to enhance the accuracy, integrity, and availability. Unfortunately, a nearby pseudolite may induce a strong interference to GPS receivers...
