This book provides a comprehensive, up-to-date description of the methodologies and the application areas, throughout the range of digital communication, in which individual signals and sets of signals with favorable correlation properties play a central role. The necessary mathematical background is presented to explain how these signals are generated, and to show how they satisfy the appropriate correlation constraints. All the known methods to obtain balanced binary sequences with two-valued autocorrelation, many of them only recently discovered, are presented in depth. The authors treat important application areas including: Code Division Multiple Access (CDMA) signals, such as those already in widespread use for cell-phone communication, and planned for universal adoption in the various approaches to 'third-generation'(3G) cell-phone use; systems for coded radar and sonar signals; communication signals to minimize mutual interference ('cross-talk') in multi-user environments; and pseudo-random sequence generation for secure authentication and for stream cipher cryptology.

现有的无线传感器网络(WSN)泛洪方面的工作主要集中在单数据包问题上,而顺序多数据包问题的工作出奇地少。 本文提出了OppCode,这是一种在WSN中用于多数据包分发的新型基于机会编码的泛洪架构,其中通常同时存在不可靠和相关的链接。 每个节点不是每次都泛洪单个数据包,而是将从特定的固定大小页面中选择的多个本机数据包编码为已编码的数据包,然后进一步重新广播。 关键思想包括两个部分。 一种是机会编码决策,其中每个节点根据每个邻居已经拥有的数据包的概率估计,贪婪地抓住每个可能的编码机会,以最大化其所有邻居的总编码增益。 另一个是寻呼的集体确认(ACK),其中一次重播不仅充当对发送方成功分发整个页面中所有数据包的隐式ACK,而且还充当概率ACK以更新针对它的邻居。 基于大量仿真和21节点测试平台的实验表明,OppCode在可靠性,传输开销, 延迟和负载平衡。

The composite binary offset carrier (CBOC) modulated signal contains multi-peaks in its auto-correlation function, which brings ambiguity to the signal acquisition process of a GNSS receiver. Currently, most traditional ambiguity-removing schemes for CBOC signal acquisition approximate CBOC signal as a HOC signal, which may incur performance degradation. Based on Galileo El CBOC signal, this paper proposes a novel adaptive ambiguity-removing acquisition scheme which doesn't adopt the approxi
