| 摘要 |
The invention provides a communication system and method of communication. The communication system includes a satellite transmitter arranged to transmit a first signal to be received within a predefined geographical area by a satellite receiver, and a terrestrial transmitter arranged to transmit a second signal to be received within the predefined geographical area by a terrestrial receiver. The first and second signals share a common radio frequency band and the system is arranged such that the first signal is received at an antenna associated with the satellite receiver at a first angle from the horizontal, the first angle being greater than a second angle from the horizontal at which the second signal is received at the antenna. This enables the satellite receiver to distinguish the first signal from the second signal. The terrestrial transmitter and receiver are also arranged to operate a multiple-input and multiple-output MIMO system enabling the terrestrial receiver to distinguish the second signal from the first signal.
