Abstract: The invention relates to a method for transmitting pilot signals used for measuring and reporting channel state information, CSI, in a multiple input/multiple output, MIMO, system, comprising: generating a pilot sequence by using a maximal-length shift register sequence, m-sequence; assigning a different shift to multiple transmit antennas, wherein the value of the shift is dependent on at least one characteristic of the communication channel; generating a pilot signal at each transmit antenna by shifting the pilot sequence by the value specified by the shift; and transmitting the pilot signal via the transmit antenna.

Abstract: A ground station antenna including a torus shaped reflector having multiple feed points along a focal arc in front of the reflector. The ground station antenna includes transceiver feeds having their electrical phase centers located on the focal arc and supported by a rotating feed platform. The transceiver feeds are configured to simultaneously track rising and falling satellites when the platform rotates. The ground station antenna further includes a wireless power receiver coupled to the transceiver feeds to power the transceiver feeds. The ground station antenna further includes a wireless signal interface coupled to the transceiver feeds to communicate signals with a base unit to perform subsequent processing.
