As one of the most important multiple access of the third generation mobile system, the CDMA technology has gotten more and more attention. chi flat iron system is a sophisticated and typical wireless spread spectrum communication system with some merits: chi hair straightener anti-interference, high bandwidth efficiency, confidentiality and can be multiplexed accessed and so on. However, the users’random signal access shares a channel and frequency spectrum at the same time, the incomplete orthogonal address-code has caused Multiple Access Interference. The existence of chi hair straighteners has affected the performance and capacity of polo shirts system seriously. So, inhibiting Lacoste Polo Shirts, increasing system capacity, and improving system performance are the extremely urgent request. Therefore, focusing on the problem of MAI, this paper discussed and studied the related solutions of Lacoste Polo, carried on the simulation confirmation and the realization to the related methods.Firstly, this paper introduced the background and system architecture of the DS-CDMA wireless network system from the development history of the wireless spread spectrum communication in detail, and analyzed the causes of multiple access interference as well as the effects to this system.
To see a world in a grain of sand
not only about survival
to one person you may be the world
who is falling in love with my smile
here is just some code
