  1. Direct sequence - code divition multiple access ( ds - cdma ) technology is achieved easily and used widely at present its receiver capability is confined by two factors, one of which is the multiple access interference ( mai ) which makes the capacity low, another of which is the near - far problem

    直接序列擴頻-碼分多址（ ds - cdma ）技術是最易實現、也是目前應用最廣的一種方式，它的接收性能受到兩個主要的限制：一個是多址干擾造成的性能下降；另一個則是遠近效應問題。
  2. For wireless communications, direct sequence code division multiple access ( ds - cdma ) techniques have received a great deal of attention due to the expectation of capacity increase, interference rejection capability, security, and so on. in a high data rate application such as multimedia services, however, the capacity of ds - cdma systems is limited by both the inter - chip, or inter - symbol interference

    Cdma技術以其高抗干擾能力、高容量、高保密性等技術優勢在第三代移動通信系統中被廣泛應用，然而在高速數據業務中，嚴重的碼間干擾和符號間干擾會導致系統性能明顯下降。
  3. Direct sequence spread spectrum ( ds ) signals have been widely used for secure communication and mobile communication known as code division multiple access ( cdma ) system. because ds signals have many advantages such as anti - jamming capability, low probability of interception, multiple access capability and so on

    直接序列擴頻通信具有低截獲概率，抗干擾能力強以及實現碼分多址等優點，因而在抗干擾通信及民用移動通信中得到廣泛的應用。
