Discrete Fourier Transform based Channel Estimation Scheme for MIMO-OFDM Communication System
نویسندگان
چکیده
A multi-input multi-output (MIMO) communication system combined with orthogonal frequency division multiplexing (OFDM) system can provide high transmission data rate, spectral efficiency and reliability for wireless communication systems. These parameters can be further improved by combating with fading, the effect of which can be reduced by properly estimating the channel at the receiver side. This paper presents a discrete Fourier transform based channel estimation scheme, which shows better performance when compared with existing channel estimation schemes like least square error (LSE) and minimum mean square error (MMSE) schemes.
