Abstract In CDMA systems multi-access interference (MAI) is a very important component resulting in poor reception performance, however parallel interference cancellation (PIC) can solve this problem to some extent. But in PIC process error cancellation of interference resulting from error decision at the former stage will influence the veracity...

In this paper, a new selective and adaptive parallel interference cancellation technique is presented for code division multiple access systems. The proposed technique performs a parallel interference cancellation in multistage, and the computational complexity is reduced by applying the cancellation to unreliable signals only. The performance of the proposed scheme is investigated through comp...

This paper introduce Fractional Delay Filter (FD) into SelfInterference Cancellation based Full-Duplex communication system. The paper explains that an accurate delay of baseband signal in cancellation channel is very important for the performance of self-interference cancellation. It emphasise that a delay other than a phase alignment can extend the cancellation to wideband with reasonable per...

When using electrical-balance duplexers (EBDs) to provide RF self-interference cancellation for in-band full-duplex, in-band distortion produced by nonlinear CMOS switches in the duplexer cause distortion that limits the headroom for additional self-interference cancellation in subsequent cancellation schemes in the transceiver. A prototype EBD is fabricated in 0.18μm SOI CMOS to investigate th...

The performance of three optics-based interference cancellation systems are compared and contrasted with each other, and with traditional electronic techniques for interference cancellation. The comparison is based on a set of common performance metrics that we have developed for this purpose. It is shown that thorough evaluation of our optical approaches takes into account the traditional noti...

Code Division Multiple Access (CDMA) system is being most popular communication technique due to its robustness & spread spectrum techniques. The CDMA include the pseudo sequences (PN-sequences) which provide the secure communication over a wide band. But the Multiple Access Interference (MAI) limits the capacity of Direct Sequence Code Division Multiple Access (DS-CDMA) based systems. For DS-C...

In this paper successive interference cancellation (SIC) based on optical code division multiple access (O-CDMA) systems has been investigated. SIC scheme refers to a family of low complexity multi-user detection (MUD) methods for direct sequence CDMA systems. Performance of optical CDMA system is influenced by multiple access interference (MAI) resulted from the overlapping between the users. ...

This paper explains about the mud for CDMA and compares different techniques available in the same field and comes out with the most effective approach. A brief explanation about interference cancellation, decorrelator mud and successive interference cancellation have been emphasized

The throughput of existing MIMO LANs is limited by the number of antennas on the AP. This paper shows how to overcome this limitation. It presents interference alignment and cancellation (IAC), a new approach for decoding concurrent sender-receiver pairs in MIMO networks. IAC synthesizes two signal processing techniques, interference alignment and interference cancellation, showing that the com...

In this paper, we introduce an echo cancellation technique for full-duplex wireless Orthogonal Frequency Division Modulation (OFDM) communication. The novelty of the work is related to improvements in the models to compensate far-end channel and transmitter front-end, not considered before. Interference cancellation is based on Least Squares (LS) algorithm performed in two successive stages, wh...
