Wireless telecommunications system that mitigates the effect of multipath fading

An apparatus comprising:

• a signal inverter for inverting and alternately not-inverting a first signal in accordance with a schedule to create a second signal;
• a first antenna for transmitting said first signal;
• and
• a second antenna for transmitting said second signal.

A method comprising:

• spreading an information signal to generate a direct-sequence spread-spectrum signal;
• time-division multiplexing said direct-sequence spread-spectrum signal with a pilot signal to generate a first time-division multiplexed pilot-aided direct-sequence spread-spectrum signal, which is partitioned into a series of time-slots;
• and
• inverting and alternately not-inverting said first time-division multiplexed pilot-aided direct-sequence spread-spectrum signal in accordance with a schedule to create a second time-division multiplexed pilot-aided direct-sequence spread-spectrum signal.

An apparatus comprising:

• a multiplier for spreading an information signal to generate a direct-sequence spread-spectrum signal;
• a time-division multiplexor for time-division multiplexing said direct-sequence spread-spectrum signal with a pilot signal to generate a first time-division multiplexed pilot-aided direct-sequence spread-spectrum signal, which is partitioned into a series of time-slots;
• and
• a signal-inverter for inverting and alternately not-inverting said first time-division multiplexed pilot-aided direct-sequence spread-spectrum signal in accordance with a schedule to create a second time-division multiplexed pilot-aided direct-sequence spread-spectrum signal.

A method comprising:

• receiving a time-division multiplexed pilot signal;
• time-division demultiplexing said time-division multiplexed pilot signal in accordance with a schedule to create an inverted information-bearing signal, an inverted pilot signal, a non-inverted information-bearing signal, and a non-inverted pilot signal;
• adjusting said inverted information-bearing signal based on said inverted pilot signal;
• and
• adjusting said non-inverted information-bearing signal based on said non-inverted pilot signal.

An apparatus comprising:

• a first multiplier for adjusting said inverted information-bearing signal based on said inverted pilot signal;
• and
• a second multiplier for adjusting said non-inverted information-bearing signal based on said non-inverted pilot signal.
