Abstract
A method of transmission in a wireless communication system including a transmitter, a transceiver and a receiver. The transmitter transmits a first signal to the receiver. The transceiver also receives the first signal and retransmits the first signal to the receiver by modifying the signal characteristics, such that the first signal and the retransmitted signal are received substantially uncorrelated at the receiver.
Claims51
A method of transmission in a wireless communication system, the method comprising:
- transmitting a first signal from a first signal source to a receiver via a first signal path;
- and
- modifying characteristics of the first signal and retransmitting the modified first signal from a second signal source via a second signal path, such that the first signal and the modified first signal are received substantially uncorrelated at the receiver, via the first and second signal paths, respectively,
- wherein the characteristics are modified based on correlation quality feedback from the receiver in a first mode and randomly assigned in a second mode.
1 more element
A wireless communication system, comprising:
- a first signal source, a second signal source, and a receiver,
- wherein the transmitter is configured to transmit a first signal from the first signal source to the receiver via a first signal path, and
- wherein the second signal source is configured to receive the first signal, modify characteristics of the first signal, and retransmit the modified first signal to the receiver via a second signal path, such that the first signal and the retransmitted modified first signal are received substantially uncorrelated at the receiver,
- wherein the characteristics are modified based on correlation quality feedback from the receiver in a first mode and randomly assigned in a second mode.
