Estimating power on spatial channels

A machine-readable medium having stored thereon data representing instructions that, when executed by a processor, cause the processor to perform operations comprising:

• receiving a signal on a conventional communications channel at a plurality of antenna elements of a third radio, the received signal including a first component from a first radio and a second component from a second radio, the first and second radios communicating with the third radio using the conventional communications channel;
• determining a first radio weight used to receive signals from the first radio;
• estimating a first radio spatial signature;
• calculating a first power estimate for the first radio using the received signal, the first radio weight and the first radio spatial signature;
• calculating a second power estimate for the second radio using the received signal;
• and
• estimating a contribution of the first component to the received signal, the estimation using the first power estimate and the second power estimate.

A communications device comprising:

• a receiver for receiving a signal on a conventional communications channel at a plurality of antenna elements of the communications device, the received signal including a first component from a first radio and a second component from a second radio, the first and second radios communicating with the communications device using the conventional communications channel;
• a processor communicatively coupled to the receiver for:
• determining a first radio weight used to receive signals from the first
• estimating a first radio spatial signature;
• calculating a first power estimate for the first radio using the received signal, the first radio weight and the first radio spatial signature;
• calculating a second power estimate for the second radio using the received signal;
• and
• estimating a contribution of the first component to the received signal, the estimation using the first power estimate and the second power estimate.
