1. An apparatus comprising:
a calculator circuit configured to generate a plurality of adjusted signals, the calculator circuit comprising:
one or more processors configured to combine a plurality of transmission signals into a plurality of sets of intermediate results, each transmission signal received from a respective wireless transmitter of a plurality of wireless transmitters,
wherein the one or more processors is further configured to sum each set of the plurality of sets of intermediate results to generate a corresponding adjusted signal of the plurality of adjusted signals;
wherein each wireless receiver of a plurality of wireless receivers is configured to receive the corresponding adjusted signal; and
wherein each intermediate processing result is weighted according to a respective weight for the corresponding adjusted signal to be generated by the set of intermediate results, the respective weight based on an amount of interference to the respective transmission signal from the corresponding intermediate processing result.
