In this paper, we propose an ICA based MIMO transceiver for time varying wireless channels.
By highly dynamic or highly time varying we mean that the channels characteristics are changing for each transmitted sample.
In case of highly time varying channels, the coefficients of the channel matrix H changes for each incoming data sample and the un-mixing becomes a challenging work for the ICA algorithms.
The MIMO SCSA-UD transceiver improves the separation performance of the batch ICA algorithms in highly time varying channels.
Though, the proposed transceiver system will increase the computational complexity as compared to the complexity of the existing MIMO system in time varying channels.
We consider both the time varying and the quasi static wireless channels.
We generate them randomly in our simulation for time varying as well as quasi static channels.
In our simulations, first, we evaluate the performance of the proposed MIMO SCSA-UD transceiver system utilizing the quasi static as well as the time varying wireless channels, without utilizing the automatic value adjustment (AVA) technique.
Simulation is performed over quasi static and time varying conditions with different values of the predefined threshold.
