A Novel Technique to Decrease BER using Waterfill Algorithm in OFDM-MIMO

Orthogonal frequency division multiplexing has lot of helpful properties over the single-carrier modulation framework; a wireless communication. Existing research is entirely focused on increasing the quantity of transmitter & receiver antennas in MIMO system. They have not analyzed the data and symbol rate in the MIMO-OFDM diversity with Modulation technique. It's may be the foremost spectrally economical technique discovered thus far, & it allays various drawback of multipath propagation that origins large errors in data& signal loss within microwave & ultrahigh frequency range. To overcome this issue, Waterfill algorithm has been discussed. It is analyzed that with increase of antennas at transmitter & Receiver sides both, BER is decrease.
