摘要
In this paper, we consider practical two-way communication schemes with blind channel estimation in TDD (Time-Division Duplex) MISO (Multi-Input Single-Output) and MIMO (Multi-Input Multi-Output) systems. In MISO system, we show that the blind channel estimation only needs to be done at the transceiver equipped with multiple antennas and this estimated channel can be efficiently utilized for both uplink and downlink communication. In MIMO system, we propose a two-stage communication scheme which begins with uplink transmission using differential space-time block codes and follows with two-way beamforming with blind channel estimation. We demonstrate that the novel schemes possess very good performance through simulations and compare it with training-based schemes.
