摘要
本文提出了一个低相关交错QAM序列族。在CDMA设置中，这些序列具有传输大量数据以及在反向链路上启用可变速率信令的能力。新的交错选择家族INQ具有周期N，归一化最大相关参数tasmacrmax由lsim a radicN界定，其中范围从16-QAM的1.17到大型M2-QAM的1.99，其中M = 2m, M = 2。允许每个用户在扩展序列的每个周期内传输m + 1位数据。这些结构在具有相同字母表的任何序列家族中具有最小的最大相关值。
A low correlation interleaved QAM sequence family is presented here. In a CDMA setting, these sequences have the ability to transport a large amount of data as well as enable variable-rate signaling on the reverse link. The new interleaved selected family INQ has period N, normalized maximum correlation parameter thetasmacrmax bounded above by lsim a radicN, where a ranges from 1.17 in the 16-QAM case to 1.99 for large M2-QAM, where M = 2m, m ges 2. Each user is enabled to transfer m + 1 bits of data per period of the spreading sequence. These constructions have the lowest known value of maximum correlation of any sequence family with the same alphabet.
