Channel Estimation Technique for MIMO-OFDM over Fast Fading Channels
نویسندگان
چکیده
A channel estimation method for multiple input multiple output (MIMO)-OFDM with fast fading channels is proposed to increase estimation quality and reduce the computational complexity. Specifically, we use a space-time correlation between channel coefficients, and compensate the ICI term. Since ICI compensation can be obtained without any pilot symbols for target OFDM block, our proposal is practical for realtime systems. The computational complexity is reduced by considering only dominant data symbols. key words: MIMO, OFDM, fast fading, channel estimation

Single-Carrier Frequency-Domain Equalization for Orthogonal STBC over Frequency-Selective MIMO-PLC channels
In this paper we propose a new space diversity scheme for broadband PLC systems using orthogonal space-time block coding (OSTBC) transmission combined with single-carrier frequency-domain equalization (SC-FDE). To apply this diversity technique to PLC channels, we first propose a new technique for combining SC-FDE with OSTBCs applicable to all dispersive multipath channels impaired by impulsive...

This paper presents a channel estimation scheme for multiple-input multiple-output with orthogonal frequency-division multiplexing (MIMO-OFDM) in fast varying Rayleigh channels. To handle rapid variation of channels within a transmission block, we propose a novel maximum a posteriori probability-based channel estimation scheme using pilot symbols. With the estimate of the channel matrix for the...

Orthogonal Frequency Division Multiplexing is an approach that can be used to combat the effect of frequency selective fading channels. Apart from spectral efficiency, reliability over fast fading channels is a primary concern in OFDM. MIMO systems offer a solution to this problem owing to the high capacity and beamforming gain. The integration of MIMO with the traditional OFDM systems allow pa...
