Adaptive Switching between Space-Time and Space-Frequency Block Coded OFDM Systems in Rayleigh Fading Channel
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. We focus on the application of space-time block codes ...
متن کاملAdaptive MLSE receiver over rapidly fading channels
This paper develops an adaptive maximum likelihood sequence estimator (MLSE) for rapidly fading channels corrupted by additive white Gaussian noise. This estimator is based on an explicit incorporation of the time-varying characteristics in channel modelling. When the multipath is caused by a few strong re#ectors, the channel is shown to be poly-periodically time varying. The channel impulse re...
متن کاملA Simple Two-stage Equalizer With Simplified Orthogonal Time Frequency Space Modulation Over Rapidly Time-varying Channels
In this work, we derive a equivalent delay-Doppler channel matrix of the Orthogonal Time Frequency Space (OTFS) modulation that has not been studied in previous literature. It has the similar structure as the banded channel matrix of OFDM systems over rapidly time-varying channels. However, the band in the equivalent channel matrix will no longer spread with the increase of the Doppler spread o...
متن کاملFading Channels and Interference Avoidance
Interference avoidance for multiaccess fading channels is considered in the paper. Slowly varying (quasistatic) and rapidly varying (dynamic) frequency selective fading channels are considered. For the former application of interference avoidance is straightforward, while for the latter interference avoidance is applied to the average channel.
متن کاملBasic binary state-space model for time-varying communication channels: uncertainty and information capacity
This paper looks at capacity achieving detection strategies for information transfer over time-varying channels. The time-varying binary symmetric channel (TV-BSC) is identified as the basic binary state-space model. Separation of entropies principles and the TV-BSC model-based state-space approach are used to determine the performance bounds for coherent and non-coherent detection over time-va...
