A single antenna interference cancellation algorithm for increased gsm capacity
IEEE Transactions on Wireless Communications, 2006 In mobile communications networks, system capacity is often limited by cochannel interference. Therefore, receiver algorithms for cancellation of cochannel interference have recently attracted much interest. At the mobile terminal, algorithms can usually rely only on one received signal delivered by a single receive antenna.

2009 IEEE 20th International Symposium on Personal, Indoor and Mobile Radio Communications, 2009 In orthogonal frequency division multiplexing (OFDM) based cellular systems, co-channel interference (CCI) from adjacent interfering base stations (BSs) operating and coexisting with the desired BS in the same frequency channel would greatly degrade the bit error rate (BER) performance of mobile receivers which are near to cell borders.

2011 IEEE Vehicular Technology Conference (VTC Fall), 2011 In the previous work, a single antenna interference cancellation (SAIC) algorithm named least mean square-blind joint maximum likelihood sequence estimation (LMS-BJMLSE) has been proposed. However, LMS-BJMLSE requires a long training sequence (TS) for channel estimation, which reduces the transmission efficiency. In another work, in order to solve this

Evaluation of Single Antenna Interference Cancellation in Asynchronous GSM Network
2005 IEEE 61st Vehicular Technology Conference, 2005 As a crucial convolution step, SAIC (single antenna interference cancellation) has been introduced into GSM system. Great capacity gain could be achieved with SAIC applied, and a feasible study is being conducted in 3GPP. Since most of GSM networks are operated in asynchronous mode, the development and evaluation of SAIC algorithm in asynchronous ...

2013 10th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology, 2013 This paper presents a full-duplex transceiver system design operating with a single channel using a single antenna for both transmitting and receiving paths. To implement such a system, the self-interference is necessary to be eliminated. From literatures on RF interference cancellation, there has not been any suitable technique to deal with a single ...

Single Antenna Interference Cancellation for GSM by Enhanced Maximum SNR Filter
2005 2nd International Symposium on Wireless Communication Systems, 2005 We presents a link level performance evaluation and comparison of single antenna interference cancellation (SAlC) and conventional receivers in a synchronous GSM network scenario. The SAIC receiver is equipped with a maximum signal to noise ratio (maxSNR) FIR filter. This interference rejection method has been proven to be very effective in suppressing

GLOBECOM '03. IEEE Global Telecommunications Conference (IEEE Cat. No.03CH37489), 2005 In the first part, an iterative receiver for joint channel estimation and cochannel interference cancellation suitable for time-division multiple-access (TDMA) cellular radio systems is proposed. The receiver is based on joint maximum-likelihood sequence estimation (JMLSE).

2006 IEEE 17th International Symposium on Personal, Indoor and Mobile Radio Communications, 2006 In this paper, a receiver structure suitable for single-antenna co-channel interference cancellation in cellular TDMA networks is studied. The receiver under investigation consists of a novel linear prefilter followed by a nonlinear detector. The task of the prefilter is to suppress non-Gaussian interference and ?simultaneously?

WizBee: Wise ZigBee Coexistence via Interference Cancellation with Single Antenna
IEEE Transactions on Mobile Computing, 2015 Coexistence of Wi-Fi and ZigBee in 2.4 GHz ISM band is a long standing and challenging problem. Previous solutions either require modifications of current ZigBee protocols or Wi-Fi re-configurations, which is not feasible in large-scale wireless sensor networks. In this paper, we present WizBee, a coexistence system using single-antenna sink without

2010 IEEE 72nd Vehicular Technology Conference - Fall, 2010 In orthogonal frequency division multiplexing (OFDM) based cellular systems, co-channel interference (CCI) would greatly degrade the bit error rate (BER) performance of cell-border users. Joint maximum likelihood sequence estimation (JMLSE) based single antenna interference cancellation (SAIC) algorithms have been under intense research. In this paper,
