https://in.mathworks.com/help/comm/ug/massive-mimo-hybrid-beamforming.html;jsessionid=7a55411b2a1e97c405f177e12115

Explore the following helper functions used by the example:

• helperApplyMUChannel.m
• helperArrayInfo.m
• helperGenPreamble.m
• helperGenPilots.m
• helperJSDMTransmitWeights.m
• helperMIMOChannelEstimate.m
