We propose a differential encoding scheme and several differential decoding schemes for asynchronous multi-user MIMO systems based on orthogonal space-time block codes (OSTBCs) where neither the transmitters nor the receiver has knowledge of the channel. First, we derive novel low complexity differential decoders by performing interference cancelation in(More)
This paper proposes a differential encoding scheme and several differential decoding schemes for a two-user MIMO system based on orthogonal space-time block codes (OSTBCs) when neither the transmitter nor the receiver knows the channel. We derive low complexity differential decoders for users with two transmit antennas based on three different decoding(More)
