LIDS Colloquium
Abstract
We present a transmission scheme for exploiting diversity given by two transmit antennas when neither the transmitter nor the receiver has access to channel state information. The new detection scheme can use equal energy constellations and encoding is simple. At the receiver, decoding is achieved with low decoding complexity. The transmission provides full spatial diversity and requires no channel state side information at the receiver. The scheme can be thought as the extension of differential detection schemes to two transmit antennas.
This is based on a joint work with H. Jafarkhani.
A short reception will follow in the Osborne Room (35-338)
