TLBO Optimized Channel Estimation for Improved Channel Quality Response

This paper presents new technique in OFDM systems for estimation of channel quality, which is a crucial for improving communication system execution in the existence of noise. While several methods have been employed for this purpose, one particularly effective approach involves using the DFT based least square channel estimation method. This approach has demonstrated efficient performance, but it also has some limitations, such as its complexity making it difficult to implement. Additionally, the traditional DFT method is only suitable for time domain estimation.
