Abstract
In this paper the Orthogonal Frequency Division Multiplexing (OFDM) is used to improve the spectral efficiency and produces a high speed of data rate. The channel estimation is used to estimate the properties of channel and reduces the complexity. Channel estimation is important parameter to improve the performance and efficiency. The greedy algorithms are used to optimize the problems when signal are not received in actually manner (signal are not received in directly). Therefore, all techniques are playing a great role to system performance. This paper provides a review of OFDM system with channel estimation in Greedy Algorithms.
