چکیده
MIMO-OFDM system is a new wireless broadband technology which has gained great popularity for its capability of high rate transmission and its robustness against multi-path fading and other channel impairments. Precise and competent channel estimation for MIMO-OFDM systems is necessary to improve error performance of the system. In this paper, Least Squares (LS) channel estimation is implemented for 2x1 and 2x2 type of OFDM systems with Alamouti technique. The results are compared and it shows that the performance of the system has been improved. KeywordMIMO, OFDM, Alamouti. Least Squares channel Estimation

متن کاملSelective Tone Reservation method for PAPR reduction in SFBC-OFDM systems
The high Peak to Average Power Ratio (PAPR) of Orthogonal Frequency Division Multiplexing (OFDM) and MIMO-OFDM systems reduces the system efficiency. In this paper, an extension of Tone Reservation (TR) method is introduced for PAPR reduction in Space Frequency Block Coded OFDM (SFBC-OFDM) systems. The proposed algorithm is based on a time domain kernel which is added to the signal of the anten...

متن کاملPAPR Reduction Scheme for MISO and MIMO OFDM Systems with Limited Feedback
For multiple-input single-output (MISO) and multiple-input multiple output (MIMO) beamforming (BF) orthogonal frequency division multiplexing (OFDM) systems employing cluster-based codebook index feedback (CCIF), a new peak-to-average power ratio (PAPR) reduction method is proposed. In the proposed method, a dummy signal is generated in null space of the channel and superimposed on the original...
