TL;DR: In this paper, a super-frame having a time-frequency resource region containing an allocation control channel and multiple pilot elements, at least some of which are associated with the control channel, is considered.
Patent
Frequency-domain MIMO processing method and system
TL;DR: In this article, a communication system based on frequency-domain MIMO processing is described, in which a transmitting device transmits weighted time-domain waveforms as a function of the weighted frequencydomain signals.
Patent
Method and device for adaptive antenna combining weights
TL;DR: In this article, a receiving device receives a plurality of time-domain Doppler channel estimates for at least one transmitter, a plurality for each of the sinusoids, and a spatial covariance matrix of a corrupting environment.
Patent
Method and device for fixed in time adaptive antenna combining weights
TL;DR: In this article, a receiving device receives at least one Doppler channel estimate and a spatial covariance matrix of a corrupting environment, which are used to create a null DoppLER spatial covariances matrix.
Patent
Method and device for multi-user frequency-domain channel estimation based on gradient optimization techniques
TL;DR: In this paper, a method of estimating the time and frequency response of a desired signal received by at least one antenna, based on gradient optimization techniques and efficient DFT processing, was proposed.
