This paper proposes a novel interference cancellation technique that prevents radio receivers from degrading due to periodic signals caused by electromagnetic waves emitted high power circuits. The proposed cancels in the frequency domain, even if drift time domain. We propose estimation based on super resolution such as ESPRIT. Moreover, we sequential enhance performance. employs linear filter...

A multiuser receiver is developed that is capable of separating receptions from independent, mobile users whose transmissions overlap in both time and frequency. With respect to any one user's Doppler corrected signal, the other communication signals appear as multiple-access interference distributed across the Doppler dimension. A previously developed receiver composed of an adaptive time-reve...

In the recent years, heterogeneous network (HetNet) is used to improve the spectral efficiency and network capacity of Long Term Evolution-Advanced (LTE-A). Although, it has huge traffic congestion due to numerous numbers of mobile users and data terminals, leads to problems of cooperation between Macro-cell and Pico-cells. One of the major interference sources in LTE-A is Common Reference Sign...

In this paper we analyze capacity losses in advanced wideband Code Division Multiple Access (WCDMA) networks due to imperfections in the estimation of the system and channel parameters. Key components in the analysis are multiple access intracell interference (MAI), intercell interference, efficiency of the interference cancellation, multipath intensity profile, efficiency of the rake combiner,...

Several channel interference cancelation techniques have been proposed in different journals aiming at lowering to asymptotic bit error floors in optical OCDMA systems. These interference cancellation techniques are classified into two groups. One is based on the use of properties of sequence codes and another is based on the use of non linear elements in OCDMA systems. Optical hard-limiter is ...

Successive interference cancellation (SIC) scheme is proposed as a new technique that has the potential to reduce the interference and suppress the multiple-access interference (MAI) in spectral-amplitudecoding (SAC) optical-code-division-multiple access (OCDMA) systems. The proposed receiver-based on fiber Bragg gratings (FBGs) techniques. The performance of the proposed system is theoreticall...

In this paper we study the effect of cancellation order on bit error rate (BER) performance of a Code Division Multiple Access (CDMA) system employing a linear Successive Interference Cancellation (SIC) receiver in both an Additive White Gaussian Noise (AWGN) channel and a Rayliegh fading channel. Four different ordering schemes are studied. We show that changing the cancellation order can lead...
