- True Parallel Processing in Artificial Neural Networks
- The area of artificial neural networks, which dates back to the early twentieth century, could only offer positive contributions to technology after the back-propagation algorithm was proposed in 1986. In this note an alternative algorithm to the gradient descent used in back-propagation is proposed. This algorithm is based on the...

- Impact of the Propagation Environment on the Performance of Space-Frequency Coded MIMO-OFDM
- Previous work on space-frequency coded MIMOOFDM has been restricted to idealistic propagation conditions. In this paper, using a broadband MIMO channel model taking into account Ricean K-factor, transmit and receive angle spread, and antenna spacing, we study the impact of the propagation environment on the performance of space-frequency coded MIMO-OFDM.
