The Code division multiple access (CDMA) and adaptive antenna system(AAS)system are two approaches that show realpromise for increasing spectrum efficiency. In this research. we investigate the performance of AAS in the CDMA transceiver. The CDMA transceiver has been developed to adaptively correct antenna impedance mismatch. https://countryscenesaddleryandpetsuppliers.shop/product-category/safety-helmets/
