Abstract
Methods, systems, and devices for channelizing and beamforming a wideband waveform are described. Generally, the described techniques provide for transmitting and receiving wideband waveforms that are beamformed on a per-channel basis during generation of the wideband waveforms. A transmitter may separate a first wideband signal into segments, with each segment bandwidth corresponding to a channel of the system bandwidth, and may map the segments to channels. The segments may be replicated to generate multiple copies of each segment. The transmitter may beamform and combine the copies of the segments to generate multiple wideband waveforms, and transmit each wideband waveform using a different antenna. A receiver may receive multiple wideband waveforms using multiple antennas and may separate each wideband waveform into segments, then beamform and de-map the segments. The techniques may be used to transmit and receive beamformed wideband waveforms over tactical data links.
