[SCM] DDSS_Matlab DL : 0: 直接序列扩频Matlab程序直接序列扩频通信可以有效地抵抗来自信道中的窄带干扰。在一个直扩通信系统中,扩频是通过伪噪声序列(PN)对发送的信息数据进行调制来实现的。在接收端,原伪噪声序列和所收信号的相关运算可将窄带干扰扩展到DS信号的整个频带,使干扰等效为幅度较低频谱较平坦的噪声；同时，将DS信号解扩,恢复原始信息数据。-Matlab procedures for direct sequence spread spectrum direct sequence spread spectrum communications can effectively resist the narrow-band interference from the channel. In a DSSS communication systems, spread spectrum pseudo-noise sequence through (PN) for sending information data modulation is achieved. At the receiving end, the original pseudo-noise sequence and the received signal related to computing can be extended to narrow-band interference signal DS the whole band, so interference is equivalent to a lesser extent than the flat spectrum of noise At the same time, the DS signal despreading and restore original information data.

[SCM] temperature DL : 0: 此设计以单片机STC89C51为核心，由声音传感器采集脉搏信号，经过LM324前置放大电路、滤波电路和比较电路后得到与脉搏相关的脉冲信号，将该脉冲信号作为定时/计数器T1中断信号交由单片机进行脉冲周期的计算，T0做定时器。然后得出每分钟的脉搏搏动次数(即心率)，并将结果1602LCD上显示心率。在对人体脉搏检测时，具有检错排错的功能。若出现误操作（如不小心移动时产生的噪声）造成检测到的心跳次数不正确的结果，所以在程序中检测时间到达第5秒时，先对其进行计算，若结果超出正常范围则自动返回重新检测，直至结果正确，再继续检测5秒，最终由单片机计算出结果。在测量数据超过正常范围(如大于120次／min或小于45次／min)时自动重新开始检测。-Single-chip STC89C51 this design as the core, by the sound pulse sensor signal acquisition, the LM324 preamp circuit, filter circuit and compare the circuit to be associated with the pulse of the pulse signal, the pulse signal as the timer/counter interrupt signal cross-T1 single-chip pulse by calculating the cycle, T0 timer so.And then concludes that the pulse per minute pulse frequency (ie heart rate), and the results show 1602LCD heart rate.

[SCM] DeblurringImagesUsingtheBlindDeconvolutionAlgorit DL : 0: The Blind Deconvolution Algorithm can be used effectively when no information about the distortion (blurring and noise) is known. The algorithm restores the image and the point-spread function (PSF) simultaneously. The accelerated, damped Richardson-Lucy algorithm is used in each iteration. Additional optical system (e.g. camera) characteristics can be used as input parameters that could help to improve the quality of the image restoration. PSF constraints can be passed in through a user-specified function

[SCM] 14.pdf.tar DL : 0: Abstract—2×2 unitary precoding based on receiver feedback is applied alongside spatial multiplexing at the base station in HSDPA (D-TxAA) when the mobile terminal supports MIMO transmissios [1]. This precoding will influence achievable sumrate of the MIMO channel if it influences the Signal-to- Interference-plus-Noise Ratio (SINR) of streams at the receiver (RX) output. We propose a set of MIMO HSDPA receivers, all based upon a LMMSE chip-level matrix filter (equalizer) front end, and introduce the notion of joint bias for the MIMO chip equalizer. Statistical properties of the spatial model thus obtained are exploited to analyze the performance of proposed MIMO receivers. It is shown that precoding choice depends upon the MIMO receiver and the extent of its impact depends on the MIMO RX.
