1. A method comprising:
- generating, by a first node, a signal to be used for an orthogonal frequency division multiplexing (OFDM) transmission, the signal based at least in part on;
a first pseudorandom sequence associated with a group of nodes that comprises the first node; and
a second pseudorandom sequence associated with a first recipient of the OFDM transmission; and
transmitting, via one or more antennas of a plurality of antennas of the first node, the signal as at least part of the OFDM transmission.

Abstract
Methods and systems are described for generating a signal, which may be based on, for example, a pseudorandom sequence associated with a group of nodes, a pseudorandom sequence associated with a recipient, and/or a complex sinusoid. The first node may transmit the signal as an orthogonal frequency division multiplexing (OFDM) transmission.
