About the Project

A major problem encountered with antenna arrays is when the bandwidth used is covering a wider spectrum. This causes beam squint and thus will affect the Signal-to-Noise Ratio (SNR) and subsequently the throughput of the whole system.

A technique could be adopted to cancel this effect either at the RF or baseband processing. The idea of this project is to design an equalizer to remove such effects even with or without the channel that exists between the transmitter and a receiver. It will be good to consider DVB-S2X and how this system can be improved.
