compressing at least a first one of the plurality of signals; and

expanding at least a second one of the plurality of signals.

5. The method of claim 1 , further comprising:

transmitting, from two or more antennas at different locations on the moving platform, a plurality of outbound signals representing second data to one or more stationary receivers.

6. A non-transitory computer-readable medium storing instructions that, when executed, cause one or more processors to perform operations comprising:

receiving a first signal that is obtained by a first antenna at a first location on a moving platform and that has a first signal distortion;

receiving a second signal that is obtained by a second antenna at a second location on the moving platform and that has a second signal distortion that is different from the first signal distortion;

combining the first signal and the second signal based on at least a result of multiplying the first signal and the second signal to obtain a resultant signal; and

transmitting the resultant signal to one or more wireless service users on the moving platform;

wherein the first location at which the first signal is obtained is at a front end of the moving platform with respect to a direction in which the moving platform is moving, and

wherein the second location at which the second signal is obtained is at a rear end of the moving platform with respect to the direction in which the moving platform is moving.

7. The non-transitory computer-readable medium of claim 6 , wherein the combining the first signal and the second signal further comprises calculating a square root of a result of the multiplying.

8. The non-transitory computer-readable medium of claim 6 ,

wherein the first signal is received from a first transmitter and the second signal is received from a second transmitter,

wherein the first antenna is closer to the first transmitter than the second antenna, and

wherein the second antenna is closer to the second transmitter than the first antenna.

9. The non-transitory computer-readable medium of claim 6 , wherein the receiving includes:

compressing the first signal; and

expanding the second signal.

10. The non-transitory computer-readable medium of claim 6 , wherein data represented by the first signal and data represented by the second signal are identical.

11. The non-transitory computer-readable medium of claim 6 , further comprising:

transmitting a third signal representing second data from the first antenna to one or more stationary receivers; and

transmitting a fourth signal representing the second data from the second antenna to the one or more stationary receivers.

12. A communication device, comprising:

at least a first antenna and a second antenna disposed at different locations on a moving platform; and

a processor, coupled to the first antenna and the second antenna, configured to:

receive a first signal that is obtained by the first antenna at a first location on the moving platform and that has a first signal distortion,

receive a second signal that is obtained by the second antenna at a second location on the moving platform and that has a second signal distortion, which is different from the first signal distortion, and

combine the first signal and the second signal to obtain a resultant signal based on at least a result of multiplying the first signal and the second signal received at the first location and the second location, respectively;

wherein the first location at which the first signal is obtained is at a front end of the moving platform with respect to a direction in which the moving platform is moving, and

wherein the second location at which the second signal is obtained is at a rear end of the moving platform with respect to the direction in which the moving platform is moving.

13. The communication device of claim 12 , wherein the processor is further configured to calculate a square root of a result of the multiplying of the first signal and the second signal to obtain the first data.

14. The communication device of claim 12 , wherein the processor is further configured to:
