Effect of ranging error on Base Station Cooperation OFDM system

Abstract

Base Station Cooperation Transmission of OFDM symbols (BSC-OFDM) is a promising approach to increase cell-edge capacity. The effect of Ranging Error on BSC-OFDM is investigated in this paper. Timing offset greater than 1 OFDM symbol in analytically duration creates asynchronous interference. Results show that a single ranging code transmitted by a mobile station provides greater capacity over a scheme with a separate orthogonal ranging code for each base station.
