For the uplink of the E–UTRA Long Term Evolution (LTE) system, single–carrier frequency–division multiple access (SC–FDMA) transmission has been selected. Frequency–domain linear and decision–feedback equalizers have been already given in the literature for an SC–FDMA transmission over a multiple– input multiple–output (MIMO) intersymbol interference (ISI)(More)
Cellular mobile radio systems like GSM/EDGE (Enhanced Data Rates for GSM Evolution) using pulse amplitude modulation (PAM) for transmission over frequency-selective channels are confronted with increasing demands on spectral efficiency. By using advanced signal processing techniques, receivers are able to cope with higher interference power levels from e.g.(More)
In Lithium-ion battery systems used for automotive traction applications a communication network is required for monitoring and control functions. We consider the power line communication (PLC) as a good alternative to data transmission buses used up to date in Lithium-ion battery systems, with the main scope consisting in reducing the cable harness and(More)
We consider a joint detection approach for cancellation of co-channel interference in time-division multiple access (TDMA) mobile communications systems like GSM/EDGE (enhanced data rates for GSM evolution). Concepts from reduced-state equalization of frequency-selective multiple-input multiple-output (MIMO) channels are applied together with prefiltering.(More)
In cellular mobile radio systems, multiple access is causing interference that limits capacity of the networks. The GSM system with multiple users can be interpreted as MIMO system with a desired user and (cochannel and adjacent channel) interferers. Using a multiple– input multiple–output (MIMO) multiuser joint detection approach for desired signal and one(More)
In this paper, a joint (multiuser) turbo equalizer performing single antenna interference cancellation (SAIC) for complex–valued modulation schemes is proposed. In order to improve the performance of a reduced–complexity equalizer for intersymbol interference (ISI) channels in different interference situations (overloaded system), an appropriate(More)
In this paper, we consider responsive communications jamming for vehicle protection against radio-controlled improvised explosive devices (RCIEDs). Unlike barrage jamming systems, which operate in an open-loop fashion, responsive jammers scan the radio spectrum on a regular basis and are thus able to react to upcoming signal activities. This allows to focus(More)
In this paper, single–carrier transmission impaired by cochannel interference is considered, which generally arises in a GSM/EDGE mobile radio network. Here, cochannel interference is created due to the reuse of the frequencies in nearby cells. In the case, that only a single antenna is available at the mobile receiver, the (multiple–input single–output)(More)
In recent years, single antenna interference cancellation (SAIC) has evolved as an attractive method to increase the capacity of single carrier mobile radio networks like GSM/ EDGE (Enhanced Data Rates for GSM Evolution) [1], [2]. Different algorithms (e.g. [3], [4]) have been developed to improve the performance of the GSM system in severely interference(More)
