Review on Channel Estimation in OFDM
Keywords:
OFDM, MIMO, Space Time Trellis Code, Frequency Index Modulation, Compressed Sensing (CS), Channel Estimation.Abstract
OFDM is a wireless connectivity technique that sends multiple data streams over a particular channel while efficiently handling inter-symbol interference and boosting the frequency and bandwidth available. Since the antenna is used for signal transmission, predicting the noise present in a noisy channel is essential. In noisy channels, the evaluation method for estimating channel can be used to explore the impact of noise on transmitted signal. Orthogonal frequency division multiplexing (OFDM) is important in wireless communication for its elevated transmission rate. Thus this paper is based on the analysis of Orthogonal frequency division multiplexing and modulation techniques in multiple input multiple output (MIMO) user.
