Abstract
Interference caused by signals transmitted by a wireless communication system can be mitigated at unintended receivers and enhanced at intended receivers. The interference created at one or more unintended receivers by a first signal transmitted from a transmitter to an intended receiver and the unintended receivers is mitigated by removing portions of a second signal that are uncorrelated with the first signal. The second signal is directed towards the unintended receivers. A third signal is enhanced at the intended receiver by allocating a portion of a transmission power associated with the removed portions of the second signal to the third signal.
Claims20
A method comprising:
- mitigating interference created at one or more unintended receivers by a first signal transmitted from a transmitter to an intended receiver and the unintended receivers by removing portions of a second signal that are uncorrelated with the first signal, wherein the second signal is directed towards the unintended receivers;
- and
- enhancing a third signal at the intended receiver by allocating a portion of a transmission power associated with the removed portions of the second signal to the third signal.
A transmitter to transmit a first signal to an intended receiver and one or more unintended receivers, mitigate interference created at the unintended receivers by the first signal transmitted by removing portions of a second signal that are uncorrelated with the first signal, wherein transmitter directs the second signal towards the unintended receivers, and enhance a third signal at the intended receiver by allocating a portion of a transmission power associated with the removed portions of the second signal to the third signal.
A non-transitory computer readable medium embodying a set of executable instructions, the set of executable instructions to manipulate at least one processor to:
- mitigate interference created at one or more unintended receivers by a first signal transmitted from a transmitter to an intended receiver and the unintended receivers by removing portions of a second signal that are uncorrelated with the first signal, wherein the second signal is directed towards the unintended receivers;
- and
- enhance a third signal at the intended receiver by allocating a portion of a transmission power associated with the removed portions of the second signal to the third signal.
