Abstract :

for wireless multimedia applications, system with higher data rate is required. Furthermore, the frequency spectrum has become a limited and valuable resource, making it necessary to utilize the available spectrum efficiently and coexist with other wireless systems. OFDM modulation is widely used in communication systems to meet the demand for ever increasing data rates. Channel estimation is one of the key challenges in OFDM. It is not possible to make reliable data decisions unless a good channel estimate is available. Many methods have been proposed for efficient channel estimation in OFDM systems. The purpose of this article is to present a survey of the published literature in dealing with compressive sensing based channel estimation of OFDM systems
