Abstract:

The base-band binary data transmission system and BER estimation system based on neural network have been built. Few realizations of the neural network have been tested. While the discrete model and simulated version are working properly, some designmanufacture problems have occurred with the VLSI chip. If another version of the chip is going to be integrated, it would probably be modular more than one chip in order to have access to all relevant points for performance evaluation. Tests performed on a discrete NN system showed a lower accuracy than the simulations. The reason for this is the lower precision and stability of statistical moments calculated by analog circuitry. However, an analog system for BER measurement has been made operational, while its integration remains for future.
