Accordingly, the interference cancellation can be accomplished while lowering the complexity of the receiver without degrading the spectral efficiency. | 01-01-2009 |
20090097432 | METHOD FOR SETTING PACKET TRANSMISSION PATH IN AD HOC NETWORK, AND NETWORK APPARATUS USING THE SAME - A method of setting a packet transmission path in a wireless communication network and a network apparatus using the same are provided. A method of setting a packet transmission path includes setting N−1 routing regions including at least one node between a source node and a destination node based on a predetermined N number of hops, N denoting an integer greater than or equal to two, and determining a node in each of the routing regions as a relay node based on a channel gain. | 04-16-2009 |
20090135945 | ECHO CANCELLATION AND ECHO CHANNEL ESTIMATION SYSTEM USING MULTIPLE ANTENNAS - Disclosed herein is an echo cancellation and echo channel estimation system that can relay transmit signals without interference with echo signals by canceling the undesired echo signals received by a relay. The echo cancellation and echo channel estimation system is designed to relay signals between a transmitter and a receiver through a relay using multiple antennas. The echo cancellation and echo channel estimation system includes a receive antenna, a preprocessing vector generation module, an echo cancellation module, and a transmit array antenna. The receive antenna receives a transmit signal from the transmitter and an echo signal via an echo channel. The preprocessing vector generation module generates a preprocessing vector and applies the preprocessing vector, the transmit signal and the echo signal, received from the receive antenna, to the echo cancellation module. The echo cancellation module cancels only the echo signal by multiplying the preprocessing vector, the transmit signal, and the echo signal. The transmit array antenna receives a retransmit signal from the echo cancellation module and resends the retransmit signal to the receiver. | 05-28-2009 |
