Description: Noncoherent receivers are attractive for pulsed UWB systems due to the implementation simplicity. To alleviate the noise effect in detecting UWB PPM signals, this letter proposes a simple yet flexible weighted noncoherent receiver structure, which adopts a square-law integrator multiplied with a window function.

Description: A FFT-based partial matched filter (PMF)
acquisition threshold setting method for fast GPS acquisition is
presented. Normal distribution and numerical fitting technique
instead of real decision variable (DV) distribution are used in
derivation to approximate the threshold expression, and the
modification method for the threshold expression is also
presented. The threshold expression is based on the individual
FFT Doppler bin false alarm probability rather than the
convention whole detector false alarm probability. The
proposed threshold expression can be adjusted according to
the false alarm probability, the noncoherent accumulation
(NCA) length and the estimated noise variance. Furthermore
we discuss the implementation of zero-padding FFT with its
advantage and limitation. The performance is superior
compared to the reference method in terms of signal-to-noise
ratio (SNR) when detection and false alarm probabilities are
used as measurement criteria.

Description: 详细讲述了直接序列扩频差分锁相环的文章，包含具体的算法结构，并附有仿真结果。-A novel differentially coherent delay-locked loop(DCDLL) for accurate code tracking is proposed for direct sequence spread spectrum systems. Due to the use of the differential
decoder and exactly one correlator, the proposed scheme avoids
the problems of gain imbalance. The tracking error variance is
derived by linear analysis. When the proposed DCDLL scheme is
applied in ranging with additive white Gaussian noise (AWGN)
channel, the performance of the proposed DCDLL scheme is
about 1.4 dB better than that of one-correlator tau–dither loop
(TDL), and near that of noncoherent DLL.

Description: IEEE经典文章，CDMA PN序列差分捕获技术，文章内容详细，对学习和从事直接序列扩频同步捕获CDMA系统设计人员有很大帮助，推荐-New differentially coherent detectors for acquisition of direct sequence spread-spectrum signals are ntroduced. These detectors are alternatives to the noncoherent detectors that have
been considered almost exclusively in the past. The proposed detectors are suitable for commercial code-division multiple-access(CDMA) systems which operate with a relatively large noise fl oor and provide a surprisingly large signal-to-noise ratio (SNR) improvement over the noncoherentdetectors of approximately 5 dB.

ISBN: 97804716495-The four short years since Digital Communication over Fading Channels became an instant classic have seen a virtual explosion of significant new work on the subject, both by the authors and by numerous researchers around the world. Foremost among these is a great deal of progress in the area of transmit diversity and space-time coding and the associated multiple input-multiple output (MIMO) channel. This new edition gathers these and other results, previously scattered throughout numerous publications, into a single convenient and informative volume.
Like its predecessor, this Second Edition discusses in detail coherent and noncoherent communication systems as well as a large variety of fading channel models typical of communication links found in the real world. Coverage includes single- and multichannel reception and, in the case of the latter, a large variety of diversity types. The moment generating function (MGF)-based approach for performance analysis, introduced by the autho
