Abstract:

As the demand for mobile wireless network increases, the radio spectrum becomes an increasingly more precious resource. This dissertation explores two important problems to increase the efficiency of radio spectral usage. The first is a novel transmitting scheme for a multicarrier relay system with direct link between source and destination. This scheme dynamically distributes the power at both the source and relay nodes between two transmitting phases and among multiple carriers according to channel state information. The second is an exploration of several new methods for practical realization of full-duplex radio communication. Among them are a time-domain transmit beamforming method and an all-analog adaptive radio interference cancellation. Critical hardware issues such as phase noise, IQ imbalance and nonlinearity are handled in our exploration. This dissertation contains results of algorithmic development, computer simulation as well as hardware implementation.
