摘要提出了一種新穎的適用于多載波碼分多址接入( mc - cdma )系統(tǒng)上行鏈路的通道估計算法。 - 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(tǒng)是近年來提出的新的擴頻通信方式,由于二維擴頻系統(tǒng)從時域和頻域上分別對數(shù)據(jù)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(tǒng)的特點,是對傳統(tǒng)的一維時域直接序列擴頻和多載波擴頻的推廣。 - 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(yōu)勢和廣闊的應用前景,成為未來高速全光通信網(wǎng)絡的備選方案之一,是目前光通信研究領域的熱點。 - It's difficult to find code division multiplex in a sentence. 用code division multiplex造句挺難的
- 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(tǒng)是采用直接序列擴頻/碼分多址( dsss / cdma )技術，在20mhz頻帶內(nèi)實現(xiàn)四路2 . 048mbps的e1鏈路數(shù)據(jù)速率的無線傳輸。本文首先分析了整個數(shù)傳設備實現(xiàn)原理，針對系統(tǒng)asic設計和優(yōu)化整機集成性能出發(fā)，提出并實現(xiàn)了基于fpga控制pm4314e1芯片的接口模塊完成對e1鏈路信號的監(jiān)控和告警功能的改進方案。
