All-Digital Self-Interference Cancellation Technique for MIMO Full-Duplex Systems
In this paper, the MIMO full-duplex system is proposed to remove self-interference signal using modified DFT based channel estimation technique. In SISO full-duplex systems only single transceiver can transmit data on either side simultaneously whereas in MIMO full-duplex systems multiple transceivers can transmit data simultaneously from both sides. During MIMO full-duplex transmission self-in...
متن کاملSurvey on Intercarrier Interference Self- Cancellation techniques in OFDM Systems
-Orthogonal Frequency Division Multiplexing (OFDM) is a multi-carrier modulation technique which divides the available spectrum into many carriers. Efficient spectrum usage makes it most desirable candidate for high data rate transmission. However the major drawback is its sensitivity to CFO which causes Inter carrier Interference (ICI). This ICI causes severe degradation of the Bit error Rate ...
متن کاملInterference Channel with State Information
In this paper, we study the state-dependent two-user interference channel, where the state information is noncausally known at both transmitters but unknown to either of the receivers. We first propose two coding schemes for the discrete memoryless case: simultaneous encoding for the sub-messages in the first one and superposition encoding in the second one, both with rate splitting and Gel’fan...
متن کاملHyper Radial Basis Function Neural Networks for Interference Cancellation with Nonlinear Processing of Reference Signal
Efficient interference cancellation often requires nonlinear processing of a reference signal. In this paper, hyper radial basis function (HRBF) neural networks for adaptive interference cancellation is developed. We show that the HRBF networks, with an appropriate learning algorithm, is able to approximate the interference signal more efficiently than standard radial basis function (RBF) netwo...
متن کاملMultiuser Detection of Cdma by Iterated Soft{cancellation (turbo Multiuser Detection) Camera-ready Copy for Multiuser Detection of Cdma by Iterated Soft{cancellation (turbo Multiuser Detection)
Multiuser detection by iterated soft{decision interference cancellation is known to achieve almost single user performance in low and moderate interference scenarios. In this paper, it is shown how this detection scheme can be further improved by adaptive calculation of the soft{decision rule. This enables a signiicantly higher number of active users signaling within the same bandwidth to be de...
