1. A communications node comprising:
a plurality of transceivers, wherein each transceiver of the plurality of transceivers is configured to transmit, receive, or both, radio frequency (RF) signals in a frequency band spanning multiple sub-bands of frequencies;
a weight processor coupled to the plurality of transceivers, the weight processor configured to calculate weighted sums of RF signals received at the plurality of transceivers to provide a plurality of streams, or to provide RF signals for transmission by the plurality of transceivers from the plurality of streams in accordance with a set of weights, or both;
circuitry configured to select a modulation and coding scheme per-sub-band and per-stream, based at least on a channel condition metric indicative of interference in the channel, wherein the channel condition metric is provided per-sub-band and per-stream; and
a decoder configured to decode each stream of the plurality of streams, or encode the RF signals for transmission, in accordance with the selected modulation and coding scheme, wherein each decoded stream of the plurality of streams comprises decoded data bits and the encoded RF signals for transmission comprise encoded data bits.
