The Carrier Phase Measurement (CPM) of GPS may achieve high precise location because of its short wavelength. While when a moving object comes into an enclosed area, GPS signal will be limited. For this paper, we propose a new indoor positioning model which aims to achieve cm-level indoor location by using CPM method. One of the most important parts of this model is to extract the most accurate carrier...
In this paper, we propose a quantized predictive precoding scheme for spatial multiplexing multiple- input multiple-output (MIMO) systems with delayed feedback. A geodesic transmit subspace prediction algorithm is designed to predict the transmit subspace for the forthcoming transmission at the receiver. An infrequently updated codebook for transmit subspace quantization is developed to improve the...
In this paper, we propose a systematic limited feedback scheme for multiple-input single-output (MISO) transmit beamforming systems under temporally correlated channels with feedback delay. At the receiver, the channel direction information for the forthcoming transmission is predicted along a geodesic on a unit complex hypersphere. The transmitter successively updates its knowledge to the channel...
This paper presents an innovative 60 GHz substrate integrated transceiver system with a broad bandwidth up to 3 GHz. To validate the proposed substrate integrated circuits (SICs) scheme, a 60 GHz wireless communication system with modulated signals is successfully demonstrated for line-of-sight (LOS) channels. The proposed integration technique of planar and non-planar structures allows the design...
