Abstract
Systems and methods for improving the reliability of a hub-spoke communications system use a first antenna and a second antenna at the hub terminal. Spread spectrum transmission from the hub terminal uses the first antenna, and the second antenna is enabled when blockage between the first antenna and any one of the spoke terminals is present. The first antenna and the second antenna have substantially orthogonal polarizations. The spread spectrum transmissions from the first antenna and second antenna have different pseudonoise code timing so that the received transmissions are offset by at least one chip interval from each other.
