ABSTRACT:
Inter-layer inter-symbol interference is avoided using diagonally layered, Multi-antenna transmissions. Known symbols are inserted at the borders between different layers to avoid inter-layer inter-symbol interference. Multiple data-streams (layers). are transmitted over multiple antennas in an effective and smart way so that inter-layer inter-symbol interference between different data-streams is avoided when changing transmit antenna for the data-streams.
