Abstract: According to the characteristic of Broadband Wireless Multimedia(BWM) system, a random access scheme based on BWM system is proposed, which can multiplex several random access signals effectively, and promote the operating factor of frequency spectrum. Moreover, the detection method of single threshold with low complexity is also implemented, which makes the system achieve better detection performance under low false detection probability. Experimental results show this scheme is feasible.
