Microphone arrays are powerful tools for noise suppression in a reverberant room. Generalized Sidelobe Canceller (GSC) that exploits Minimum Variance (MV) criterion is efficient in interference suppression when there is no correlation between the desired signal and the interferences. Correlation between the desired signal and any of interference produces a desired signal cancellation and degrad...

We consider the convergence in norm of several iterative implementations of linear multiuser receivers, under the assumption of long random spreading sequences. We find that asymptotically, linear parallel interference cancellation diverges for systems loads of greater than about 17%. Using known results from the theory of iterative solutions for linear systems we derive optimal or near optimal...

Interference cancellation system (ICS) for 3GPP/LTE system is the broadband cancellation system, which receives forward signal through the donor antenna. We proposed new algorithm of received signal with pilot and non-pilot design. Although repeater design needs our project, so in this paper we discuss about interference cancellation algorithm for 2x2 MIMO systems without pilot in LTE. First ex...

The Multi-Code (MC) multirate DS-CDMA (Direct Sequence-Code Division Multiple Access) transmission system’s performance is analyzed, associated to aMultistage Parallel Interference Cancellation (MPIC) structure, with hyperbolic tangent decision device in the intermediate stages. Extensive Monte Carlo Simulations (MCS) considering total and partial cancellation in Additive White Gaussian Noise (...

This paper presents a miniaturized EPR spectrometer based on a single-chip transceiver. Utilizing a novel on-chip self-interference cancellation circuit, the electromagnetic coupling from the transmitter (TX) to the receiver (RX) is minimized, allowing simultaneous achievement of large TX output power and low RX noise figure (NF). In the measurement, the RX achieves a NF of 3.1 dB/6.3 dB at 10 ...

This paper studies the reception zones of a wireless network in the SINR model with receivers that employ interference cancellation (IC). IC is a recently developed technique that allows a receiver to decode interfering signals, and cancel them from the received signal in order to decode its intended message. We first derive the important topological properties of the reception zones and their ...
