OFDM/ OFDMA in 4G LTE - Part 1 • How can we Stream a Full hd movies seamlessly; Which seemed impossible in legacy networks i.e 2G? What makes 4G/LTE so fast? • In this video we have shown, What are the complexities associated with wireless channel and how they are overcome. • We have discussed why wideband single channel are inefficient for transmission. We have shown how the effect of delay spread was reduced by dividing the wideband single channel into small subcarriers. • We have also shown how multi fold throughput was achieved by the introduction of orthogonality in FDMA. • Enjoy the video. • HAPPY LEARNING • • Reference: • Images - Google images, Openclipart • Music - Bensound, Google youtube audio library • Content - 1.
