Information Transmission

The research work of the Information Transmission Group is focused on new methods for future wireless communication systems. The general goal is to contribute to the development of the theory in this field, and to find advanced techniques allowing the most efficient use of radio frequencies and transmit power. The whole work is based on vector-valued transmission models developed in the past by this group. It includes transmission over multiple-input multiple-output channels, spreading in space, time and frequency, coherent and non-coherent space-time and space-frequency coding, and iterative detection methods. Single carrier as well as multi carrier (orthogonal frequency division multiplexing, OFDM) modulation schemes are considered.
