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 channel 33 are assumed to allocate to LTE Uplink, and channel 35 and lower 4 MHz of channel 36 are assumed to allocate to Downlink. However, the interference effect of LTE on DTV has to be taken into account. Therefore, according to the interference probability of 5% required by DTV receiver and the allowable transmit power of LTE Base Station (BS) and Mobile Station (MS), the protection distance from the reference LTE BS and MS to DTV receiver and the guard band will be analyzed by using Spectrum Engineering Advanced Monte-Carlo Analysis Tool (SEAMCAT).
As a result, in the case that 8 MHz guard band is required and the assumed emission mask of LTE BS is used, the required protection distance between the LTE BS and DTV receiver is about 2 km. In the case of interference between LTE MS and DTV receiver considering the assumed emission mask of LTE MS, the protection distance is negligible above 8 MHz of guard band. The results can be as a guideline and reference in making plan for the coexistence of LTE and DTV.
