In this study, a repeated correlative coding scheme is proposed to combat the inter-carrier interference (ICI) caused by the frequency offset in orthogonal frequency division multiplexing (OFDM) communication systems. This proposed scheme combine two ideas of the well-known methods, which are the coding of adjacent subcarriers with antipodal of the same data symbol (ICI self-cancellation) and c...

Successive interference cancellation (SIC), in conjunction with orthogonal convolutional codes, has been shown to approach the Shannon capacity for an AWGN channel [1]. However, multi-cell fading wireless channels induce error in the amplitude and phase estimates required to perform perfect cancellation of the interference. By combining SIC with an appropriate power control algorithm [2], we sh...

The mitigation of co-channel interference (CCI) and inter-symbol interference (ISI) has been a major area of focus of researchers in wireless communications. An approach of interest separates CCI cancellation and ISI equalization in a slow frequency-selective Rayleigh fading channel into two stages. A space-time filter reduces the CCI, followed by a Viterbi equalizer for ISI equalization. The c...

Broadband wireless interference in a computer platform is the result of multiple dynamic electromagnetic emission sources. This interference is non-Gaussian and a receiver design based on the Gaussian assumption will yield suboptimal performance. In fact, it has a double-sided K-distribution and needs to be treated differently in the design process. When dealing with this type of interference i...

In this paper, we investigate the capacity of known interference channel, where the receiver knows the interference data but not the channel gain of the interference data. We first derive a tight upper bound for the capacity of this known-interference channel. After that, we obtain an achievable rate of the channel with a blind known interference cancellation (BKIC) scheme in closed form. We pr...

The potential of multiantenna interference cancellation receiver algorithms for increasing the uplink throughput inWLAN systems such as 802.11 is investigated. The medium access control (MAC) in such systems is based on carrier sensing multiple-access with collision avoidance (CSMA/CA), which itself is a powerful tool for the mitigation of intrasystem interference. However, due to the spatial d...

This paper proposes and analyzes an iterative power control scheme for use with successive interference cancellation (SIC) in the presence of cancellation errors. In [1], SIC is shown to increase the capacity of cellular CDMA systems significantly, even if the signal cancellation is imperfect due to estimation errors. However, an important complication of SIC relative to conventional CDMA recei...

In this paper we introduce an advanced mean field method to correct the inherent bias of conventional subtractive interference cancellation in Code Division Multiple Access (CDMA). In simulations, we get a performance quite close to that of the individual optimal exponential complexity detector and significant improvements over current state-of-the-art subtractive interference cancellation in a...

We propose a multistage multi-user detector for Code Division Multiple Access that implements Mean-Field Annealing. Annealing is a well known technique to avoid local minima in detection and optimisation problems. Local minima certainly occurs in CDMA multi-user detection leading to anomalous Bit Error Rate curves. Annealing is implemented as a standard multi-user detector implementing interfer...
