Interference analysis of DTV into LTE uplink systems
نویسندگان
چکیده
In this paper, to investigate the effects of interference resulting from the standard setting of Block Edge Mask (BEM), assuming the use of LTE systems in the Digital Dividend, the minimum separation distances according to the size of guard band between DTV transmitter and LTE base station for a specific BEM are calculated.

Study on Coexistence between Long Term Evolution and Digital Broadcasting services
Korea has made a plan to transfer from analog television to Digital Television (DTV). Therefore, TV White Spaces (TVWS)are the unused TV broadcast channels which can be available for wireless communication systems. This paper assumes that DTV operates on Channel 34 and Long Term Evolution (LTE) is assumed that it uses Frequency Division Duplexing (FDD), and then upper 4 MHz of Channel 32 and ch...
متن کاملApplying Beamforming to LTE Base Station for Reducing Interference Impact and Saving Frequency
This paper assumes that Long Term Evolution (LTE) will be deployed in TV White Spaces (TVWSs). Beamforming is a technology that is applied to an LTE base station (BS) for reducing interference impact of LTE on DTV. A simulation method based on Monte Carlo is proposed to evaluate the interference probability in DTV receivers in the case of interference impact of LTE BS on DTV receiver. As per si...
متن کاملReproducible LTE uplink performance analysis using precomputed interference signals
The consideration of realistic uplink inter-cell interference is essential for the overall performance testing of future cellular systems, and in particular for the evaluation of the radio resource management (RRM) algorithms. Most beyond-3G communication systems employ orthogonal multiple access in uplink (SC-FDMA in LTE and OFDMA in WiMAX), and additionally rely on frequency-selective RRM (sc...
متن کاملLTE and Future DTV Compatibility Study in the UHF band in Nigeria
This paper presents a compatibility study between future digital television (DTV) and Long Term Evolution (LTE) in the UHF band using Nigeria as a case study. This is done by carrying out an adjacent interference analysis to evaluate the impact of LTE base station on DVB-T2 reception using SEAMCAT software. Results obtained from simulations suggest that deploying LTE in an adjacent band would r...
متن کاملSuppression of CFO Effect in LTE Uplink Transmission: A Survey
The third generation partnership project (3GPP) Long Term Evolution (LTE) is the latest technology to tackle the increased need for mobile broadband services. Single-Carrier Frequency-Division Multiple Access (SC-FDMA) technology is being used for uplink (UL) transmission. In this system, the orthogonality between subcarriers is disrupted due to the presence of Carrier Frequency Offsets (CFOs) ...
