Design & Development of Channel Estimation Techniques for OFDM System

The general approach to channel estimation is to insert known reference pilot symbols into the transmission. Channel estimation is used for increasing the capacity of orthogonal frequency division multiple access (OFDMA) systems by improving the system performance in terms of bit error rate. It is required at the wireless communication receiver. Channel estimation and interpolation techniques are very much useful in massive MIMO in 5G which is very much important in the internet of things (IoT).
