系统设计方案 Fast settling-time added to the already conflicting requirements of narrow channel spacing and low
Fast settling-time added to the already conflicting requirements of narrow channel spacing and
low phase noise lead to Fractional4 divider techniques for PLL synthesizers. We analyze discrete "beat-note spurious levels from arbitrary modulus divide sequences including those from classic accumulator ...
人工智能/神经网络 he algorithm is equivalent to Infomax by Bell and Sejnowski 1995 [1] using a maximum likelihood form
he algorithm is equivalent to Infomax by Bell and Sejnowski 1995 [1] using a maximum likelihood formulation. No noise is assumed and the number of observations must equal the number of sources. The BFGS method [2] is used for optimization.
The number of independent components are calculated using ...
DSP编程 The TMS320VC5506/C5507/C5509A USB peripherals can be clocked from either the USB APLL or the USB DP
The TMS320VC5506/C5507/C5509A USB peripherals can be clocked from either the USB APLL or the
USB DPLL. Since the APLL is inherently more noise tolerant and has less long-term jitter than the DPLL,
it is recommended that you switch to it for any USB operations.
matlab例程 Consider a BPSK and a QPSK system for the following two cases: 1) The probability that the symbol 1
Consider a BPSK and a QPSK system for the following two cases: 1) The probability that the symbol 1 is sent and the probability that the symbol 0 is sent are all the same. 2) The probability that the symbol 1 is sent is two times than the probability that the symbol 0 is sent. Assume that the noise ...
技术资料 电磁兼容工程
特别经典的电磁兼容书籍，作者Henry W.Ott。是在之前《noise reduction techniques in electronic systems 》第二版基础上补充了大量内容的新书。任何电子、电气工程师都应该学习。
单片机编程 无线通信网络基本概念及设计
This white paper raises some fundamental issues the design engineer should address before deciding upon a communication approach for a wireless network. As no universal wireless network solution exists, it should be custom tailored to suit the application demands. Defining your application communica ...
系统设计方案 A new PLL topology and a new simplified linear model are presented. The new fractional-N synthesizer
A new PLL topology and a new simplified linear model are presented. The new fractional-N synthesizer presents no reference spurs and lowers the overall phase noise, thanks to the presence of a SampleJHold block. With a new simulation methodology it is possible to perform very accurate simulations, w ...

The exercise should be finished in English.
2. According to Prof. Zhang s requirement, this exercise mainly focuses on the BER performance of some wireless communication system using specific coding and modulation type through the AWGN channel. Signal-to-Noise ration (SNR) varies from 5dB to 20dB.
