  4. The technology of direct sequence spread spectrum / code division multipul access ( dsss / cdma ) are applied in the broadband code division multiplex wireless communication systems, which means transmitting data at the rate of 2. 048mbps using four e1 lines within the band of 20mhz. in this paper, the theory of the whole debice is first analysized specified for the system asic design and optimizing its performance

    寬帶碼分復用無線傳輸系統是採用直接序列擴頻/碼分多址( dsss / cdma )技術,在20mhz頻帶內實現四路2 . 048mbps的e1鏈路數據速率的無線傳輸。本文首先分析了整個數傳設備實現原理,針對系統asic設計和優化整機集成性能出發,提出並實現了基於fpga控制pm4314e1晶元的介面模塊完成對e1鏈路信號的監控和告警功能的改進方案。
  5. Optical code division multiplex access ( ocdma ) is a novel kind of technologies which combines with the features of wireless cdma and optical fiber communications and has strongly technical advantages and widely applied perspectives. it is one of the possible resolutions for future all optical communication network, which is a hot topic in optical communication research

    光碼分多址( opticalcodedivisionmultiplexaccess , ocdma ) ,是將無線cdma技術與光纖通信技術相結合的一種新技術,結合了兩種通信方式的特點,具有很強的技術優勢和廣闊的應用前景,成為未來高速全光通信網路的備選方案之一,是目前光通信研究領域的熱點。
  6. Multicarrier wireless communications have been widely investigated in the past decades. recently, two - dimensional spread spectrum ( 2d - ss ) system has drawn a lot of attention because of its full utilization of spreading characteristics in the frequency domain and time domain. compared with multicarrier code division multiplex access ( mc - cdma ), 2d - ss system can effectively mitigate multiple access interference ( mai ) due to spreading in the time domain

    當前多載波無線通信技術得到了廣泛的研究,二維擴頻通信系統是近年來提出的新的擴頻通信方式,由於二維擴頻系統從時域和頻域上分別對數據信號進行頻譜擴展,因此它同時具有時域擴頻和頻率擴頻通信系統的特點,是對傳統的一維時域直接序列擴頻和多載波擴頻的推廣。
