conveying at least part of the power of each transmission to each of two or more receivers; and modifying the allocation of power of a transmission to the receivers such that the spectrum utilization is greater than if each receiver were to receive the same transmission power from each transmission from each transmitter. ### Claim 8 (depends on 7) The method of claim 7, further comprising: modifying the PSD of the transmitters wherein a transmitter is notified that a receiver does not at a particular time require full bandwidth, the transmitters transmit less than full power to the receiver, the transmitters transmit to other receivers the difference between full bandwidth and the bandwidth transmitted to said receiver at the particular time, and the quality of signals to be received will be increased by greater bandwidth transmitted or decreased by lesser bandwidth transmitted. ### Claim 9 (depends on 8) The method of claim 8, further comprising: storing in system memory the PSD for all transmitters prior to modification of the PSD, and storing in system memory the PSD for all transmitters after the modification of the PSD. ### Claim 10 (depends on 9) The method of claim 9, further comprising: synchronously switching the transmitters from the modified PSD to the unmodified PSD, when system requirements change such that a switch will increase the spectrum utilization. ### Claim 11 (depends on 10) The method of claim 10, further comprising: maintaining system stability during the synchronous switching from one PSD configuration of the transmitters to another PSD configuration of the transmitters, by switching only to a configuration that is more stable that the one PSD configuration of the transmitters. ### Claim 12 (depends on 7) The method of claim 7, further comprising: modifying a precoder configuration while the precoder is active; and modifying a PSD configuration while the precoder is active; wherein the precoder configuration and the PSD configuration are modified independently of one another. ### Claim 13 (depends on 12) The method of claim 12, wherein precoder configuration is modified with an LMS algorithm and the PSD configuration is modified with an LMS algorithm. ### Claim 14 (depends on 7) The method of claim 7, further comprising;
