single antenna Interference Cancellation saic for gsm networks
Vehicular Technology Conference, 2003Co-Authors: A Mostafa, R Kobylinski, Ivica Kostanic, M AustinAbstract:This paper presents field trial results for downlink Interference Cancellation in a live GSM network. Uplink Interference Cancellation techniques have been developed in the past, which exploit the use of multiple receive antennas. However, downlink techniques are typically limited to just the use of a single receive antenna due to space limitations, cost considerations and aesthetics associated with current mobile station designs. A prototype mobile station, using a low complexity single antenna Interference Cancellation (SAIC) algorithm, was constructed, and used to assess the network gain in both asynchronous and synchronous GSM networks. The performance results measured show that SAIC techniques can provide significant gains in C/I. In addition, network simulations indicate that this same algorithm can support voice capacity gains of 39-57%. Thus, SAIC is seen to be a very viable technology for GSM capacity improvement, which can be realized in the next generation of mobile stations.

Interference Cancellation (SAIC) Method in GSM Network
2004Co-Authors: Ayman A. MostafaAbstract:Cancellation in single-valued modulation is presented. The proposed technique is based on blind Interference Cancellation and adaptive signal processing filtering and it requires use of only one receive antenna element. The paper discusses the advantages of the proposed algorithm over other single antenna Interference Cancellation algorithms reported in the literature. The paper also presents governing equations for the proposed algorithm and the Interference Cancellation performance when the signal of interest is corrupted with a single dominant co-channel interferer or multiple interferers. The algorithm is evaluated for GSM GMSK modulated signals under several cases of radio channel fading and mult i-path profiles using computer simulation. The algorithm is shown to be suitable for terminal applications where algorithm complexity is a prime concern.

Spatial Interference Cancellation Algorithm
2009 IEEE Wireless Communications and Networking Conference, 2009Co-Authors: Rizwan Ghaffar, Raymond KnoppAbstract:Future wireless communication systems characterized by tight frequency reuse, adaptive modulation and coding schemes and diversified data services will be Interference limited by interfering signals of diverse rates and strengths. We propose in this paper a low complexity algorithm for spatial Interference Cancellation in the presence of one strong interferer. This algorithm is based on an earlier proposed low complexity max log MAP detector. It encompasses two strategies for Interference Cancellation which have been termed as partial Interference Cancellation (PIC) and absolute Interference Cancellation (AIC). Their corresponding selection in the receiver is dictated by the relative strength and the rate of interfering stream. In the scenario of interfering stream being relatively weak or of higher rate as compared to the desired stream, the mobile station (MS) resorts to PIC while when the interfering stream is relatively stronger or is of lower rate, the MS switches to AIC. Finally we analyze the performance of proposed algorithm by simulations.
