This paper investigates sound source localisation using an ad-hoc microphone array, where
the microphones arbitrarily distributed in a room without knowledge of their locations. The …

In this paper, we apply iterative detection to typical time hopping (TH) pulse position
modulation (PPM) ultra wideband (UWB) spread spectrum systems. Unlike a typical TH-PPM …

Self-encoded multiple access (SEMA) is a unique realization of random spread spectrum. As
the term implies, the spreading code is obtained from the random digital information source …

Self-encoded spread spectrum (SESS) is a novel modulation technique that acquires its
spreading sequence from the randomness of an input data stream rather than through the …

在扩展频谱通信中, 扩频序列的性能与系统的抗多址干扰, 抗多径衰落的能力,
和信号的低截获率概率有密切关系, 也关系到捕获与同步系统的实现. 扩频序列的特性对扩频 …

Self-encoded spread spectrum (SESS) employs non-deterministic spreading codes that
have been generated from the random information source and provide unique advantages …

Self-encoded spread spectrum (SESS) is a novel modulation technique that acquires its
spreading code from a random information source, rather than using the traditional pseudo …

Self-encoded spread spectrum systems derive spreading codes from the data stream and
have been shown to achieve a 3 dB power gain while providing time diversity for robust …

Self‐encoded spread spectrum (SESS) incorporated with binary‐offset‐carrier modulation
can significantly improve the navigation accuracy exploiting the inherent temporal diversity …

Self-encoded spread spectrum eliminates the need for traditional pseudo noise (PN) code
generators. In a self-encoded multiple access (SEMA) system, the number of users is not …
