in this paper, we propose a technique of artificial intelligence called adaptive neuro fuzzy inference system (anfis) for canceling maternal electrocardiogram (mecg) in fetal electrocardiogram extraction (fecg).this technique is used to estimate the mecg present in the abdominal signal of a pregnant woman. the fecg is then extracted by subtracting the estimated mecg from the abdominal signal. p...

Interference cancellation is widely used in a number of application such as acoustic and speech signal processing, data communication, biological signal acquisition etc. Many papers with different approaches have been reported to cancel interferences in biosignals. This paper provides a survey of existing methods for interference cancellation in ECG signal, FECG signal, EEG signal, and EMG sign...

In this work, a linear DS-CDMA receiver utilizing soft feedback interference cancellation, is analyzed. To be able to meet diverse QoS requirements, we introduce a power control scheme that takes into account multi-QoS objectives, as well as the impact of imperfect interference cancellation. Our results are general and provide a framework for capacity comparison for many proposed linear success...

Successive interference cancellation techniques have the potential to reduce the interference and therefore increase the capacity of cellular radio systems. In this work, we analyze a linear DS-CDMA receiver utilizing soft feedback interference cancellation. To be able to meet diverse QoS requirements, we introduce a power control scheme that takes into account heterogeneous service levels as w...

Co-site interference is a problem found everywhere from wireless systems and environmental sensors to military communications; it refers to the difficulty of extracting or detecting a weak signal in proximity to a strong transmitter. Traditional interference cancellation techniques are electronics-based and their performance is consequently bandwidthlimited; electronic interference cancellation...

The existing mobile communication system suffer from problems like frequency selective fading and multi-path signals, multiple access interference due to imperfect nonorthogonal codes and narrow band interference due to coexisting systems. Multi-carrier Code Division Multiple Access (MC-CDMA) technique can combat these problems efficiently owing to its inherent properties. The objective of this...

The adaptive interference cancellation algorithms(AICA) is proposed in this paper. The Matlab simulation results of the performance of six different kinds of AICA are presented. According to the comparison of the simulation results, especially the usage of resource, convergence rate and effects of cancellation, the NLMS adaptive interference cancellation algorithm and frequency-domain block LMS...

In this paper, Selective Adaptive Parallel Interference Cancellation (SA-PIC) technique is presented for Multicarrier Direct Sequence Code Division Multiple Access (MC DS-CDMA) scheme. The motivation of using SA-PIC is that it gives high performance and at the same time, reduces the computational complexity required to perform interference cancellation. An upper bound expression of the bit erro...

The potential capacity gains of coordinated processing in the reverse link of a cellular system are evaluated. Three different matched filter-based receiver schemes, successive intra-cell interference cancellation, successive intraand intercell interference cancellation, and centralized successive interference cancellation, are analyzed considering different path loss exponents and various limi...
