摘要：
Multiple TVBDs with different TVWS channel under Korean TVWS regulation in the same pixel can cause harmful interference to DTV receiver. To overcome this problem, we propose an optimization method for multiple TVBDs with multiple TVWS channels to minimize the interference to DTV, to maximize the total capacity, and to maximize the TVBD power for its coverage expansion. The two-dimensional genetic algorithm with a pixel based interference analysis using the location probability is applied to calculate the optimal solution for the power of multiple TVBDs in the same pixel.
