When the gain of a wireless repeater is larger than the isolation between transmit and receive antennas of the repeater, the feedback signal that comes into the receive antenna from the transmit antenna of the repeater causes the repeater to go into feedback oscillation regardless of the input signal. In this paper, we propose adaptive equalizer and phase noise compensator in order to effectively...
In this paper, we propose a wireless repeater with DFE (decision feedback equalizer) based on LDPC (Low Density Parity Check) codes. So as to meet ever increasing requirements on higher wireless access data rate and better quality of service (QoS), the wireless repeater system studied. In the wireless repeater, the feedback channel and RF impairments such as phase noise, carrier frequency offset,...
In this paper, we propose adaptive equalizer and compensation of ICI (Inter carrier interference) in the wireless repeater system based on OFDM in order to effectively cancel feedback channel and phase noise. When the gain of a wireless repeater is larger than the isolation between transmit and receive antennas of the repeater, the feedback signal that comes into the receive antenna from the transmit...
