Abstract: Disclosed herein are systems, circuits, architectures and methods related to front-end architectures for wireless devices configured for uplink carrier aggregation. The disclosed methods dynamically route signals from a filter-less module to one of two modules with filters for filtering. The re-use of filters reduces the size of the filter-less module relative to a module that utilizes its own filters, thereby reducing costs, reducing size, and/or providing additional space for other modules or other functionality to be included in a wireless device.

Abstract: The present disclosure provides a method for determining a Doppler frequency shift of a wireless signal directly reflected by a moving object. An example method includes eliminating a random phase shift caused by non-synchronization between a wireless transmitting device and a wireless receiving device by using conjugate multiplication of the channel state information (CSI) on two antennas, thereby obtaining the complete Doppler frequency shift information from the phase information of the channel state information. The example method eliminates the effect on the Doppler frequency shift caused by frequency information of static paths in a manner of removing the mean, thereby obtaining an accurate frequency estimation of the moving object. A Multiple Signal Classification (MUSIC) algorithm may be used to estimate a frequency spectrum according to practical sampling intervals to avoid an effect on the frequency estimation accuracy caused by uneven sampling rate in a practical wireless transceiving system.
