Kalman Filtering for Space-time Coded Transmissions over Frequency-selective Rayleigh Fading Channels
نویسندگان
چکیده
The problem of multichannel estimation for space-time coded transmissions over frequency-selective Rayleigh fading channels is addressed. Under fast fading conditions, receivers employing Kalman filtering and moderate complexity equalization schemes are proposed for both space-time block codes (STBCs) and space-time trellis codes (STTCs). Simulation results of the proposed receivers demonstrate good performance.

Space-time coding and Kalman filtering for time-selective fading channels
This letter proposes a novel decoding scheme for Alamouti’s space–time (ST) coded transmissions over time-selective fading channels that arise due to Doppler shifts and carrier frequency offsets. Modeling the time-selective channels as random processes, we employ Kalman filtering for channel tracking in order to enable ST decoding with diversity gains. Computer simulations confirm that the prop...
متن کاملSpace-time-frequency coded OFDM over frequency-selective fading channels
This paper proposes novel space-time-frequency (STF) coding for multiantenna orthogonal frequency-division multiplexing (OFDM) transmissions over frequency-selective Rayleigh fading channels. Incorporating subchannel grouping and choosing appropriate system parameters, we first convert our system into a set of group STF (GSTF) systems. This enables simplification of STF coding within each GSTF ...

This work explores the performances of Space-Time and Space Frequency Coded Orthogonal Frequency Division Multiplexing (OFDM) with simple two branches transmit diversity scheme. The combination of multiple-antenna and orthogonal frequency division multiplexing (OFDM) provides reliable communications over frequency selective fading channels.

متن کامل12.1 Space-Time Coding and Kalman Filtering for Diversity Transmissions through Time-Selective Fading Channels (Invited)
Most existing space-time (ST) coding schemes have been developed for fiat fading channels. To offer antenna diversity gains, they rely on channel state information (CSI) acquired at the receiver through training, or, via blind channel estimation. Differential ST modulation obviates the need for (7S1 but is less effective in rapidly fading environments. This paper develops novel ST coders and de...
متن کاملFactor Graph Based Derivation of a Receiver for PCC Coded Transmissions over a Frequency Selective Fading Channel
In previous work, we presented a receiver to detect and decode parallel concatenated convolutional (PCC) coded transmissions over a frequency selective Rayleigh fading channel. This scheme generalized work by Valenti and Woerner to frequency selective channels. It was shown that re-estimation of the channel after each PCC decoding iteration yields significant gain. In this paper we present a de...
