        abstract = {Channel estimation is necessary in wireless communication systems that are affected by noise as well as multipath fading. In this project, a Pilot Symbol Assisted Modulation (PSAM) method of channel estimation is designed using VHDL and simulated using Vivado software. The input signal is changed, and different channel conditions are analyzed by observing the spikes in the output. The changes in the input signal are used to mimic the noise conditions, similar to the AWGN channel in actual communication systems. Small spikes indicate low noise conditions, while large changes indicate high channel disturbance. The interpolation method is used to smooth the output, as shown by the spikes, which makes the channel estimation process stable.},
