About this document
Spatial Reciprocity in FDD Radio Channels by cksmer is a document available to read on EtoBox.
The document summarizes research on the spatial reciprocity of uplink and downlink radio channels in frequency division duplex (FDD) systems. It finds that: 1) Previous studies have had limitations and drawn contradictory conclusions about whether the spatial channel characteristics are similar between uplink and downlink frequencies. 2) The document presents new measurement results from a study in Helsinki that used a moving transmitter and a base station with an 8-column antenna array to characterize ch
