Abstract

A method for masking communication signals, in particular for masking terrestrial RF transmission signals on board an aircraft, comprising the steps of: parallelizing a first information data stream to be transmitted on a first LTE transmission channel, the first LTE transmission channel Having a first channel transmission bandwidth and at least one guard band adjacent to the channel transmission bandwidth; distributing the first information data stream on a plurality of mutually orthogonal data subcarriers within the first channel transmission bandwidth; generating a CAZAC sequence; at least Interspersing the generated CAZAC sequences on guard band subcarriers within a guard band; and transmitting a first information data stream on data subcarriers in parallel with the CAZAC sequences on the guard band subcarriers.

Description

technical field [0001] The present invention relates to a method for masking mobile communication signals, in particular a method for masking mobile communication signals on board an airplane or other moving aeronautical vehicle. The invention also relates to an evolved Node B with a masking function for masking land mobile communication signals, in particular an evolved Node B with masking function for masking land mobile communication signals on an airplane or other mobile aviation vehicle. Background technique [0002] Currently, passengers in airplanes are required to deactivate their mobile RF communication devices at least during takeoff and landing. Mobile RF devices attempt to stay connected to terrestrial cellular networks on the ground. Due to the high speed and increased altitude of the aircraft, large path loss, high fading and delay interference can occur, forcing the internal transceivers in the mobile device to operate at full power. In addition to the RF in...
