Broadband Indoor Wireless System with In-Cell Frequency Reuse Based on Sectored Antennas

Abstract

frame, is in the NP-complete class of problems, so it can not be solved in real time. Therefore, a sub-optimum algo rithm named First Fit Algorighm is proposed for the frame scheduling problem. The problem is investigated experimen tally for a sectorization level of ten (using ten antenna sectors in the base station). A statistical model of multipath propaga tion is used to extend the results to other levels of sectoriza tion. The proposed system can significantly increase capacity when compared with systems that can transmit a single data packet per time slot. For example, while previous systems can transmit only one packet at a time, the proposed system can transmit on average close to three packets per time slot when operating with a capture threshold of 10 dB and ten an tenna sectors in a closed indoor location with internal walls of concrete blocks.
