[Program doc] extended_reciever

Description: Bit Error Rate analysis of an Extended Receiver for Rectangular PAM. The performance of a digital communication system in the presence of additive white Gaussian noise (AWGN) can be assessed by the measurement of the bit error rate (BER). The Simulink model provided is a rectangular polar pulse amplitude modulation (PAM) baseband system with an AWGN channel and an extended sample and hold receiver with a low pass filter. An extended receiver has an odd number of sample and hold circuits. What remains to be answered is if such a receiver would provide a more desirable BER than that of a simple S/H receiver.-Bit Error Rate analysis of an Extended Receiver for Rectangular PAM.

[Industry research] Signal

Description: 分析了在超宽带通信系统中的扩频干扰，并用两种通用的调制技术实现了对提出的抗干扰方法的仿真-he ultra wideband (UWB) interference to direct sequence spread spectrum (DSSS) receiver is analyzed. Two popular UWB modulation schemes, the time hopping pulse position modulation (TH-PPM) and time hopping pulse amplitude modulation (TH-PAM), are considered. The pulse repetition rate (T’RR) of UWB signal and the freqnency hand of the DSSS play the primary roles in the BER performance of the DSSS receiver in the presence of UWB interference. The UWB signal parameters raising the interference to DSSS receiver are discussed. The characteristics of an aggregation of multiple UWB signals are somehow different from that of a single UWB device, especially for the TB-PPM scheme, where discrete spectral lines maybe exist in the band of DSSS receiver. The system parameters of TH-PPM such as the modulaiion index and maximum shift incurred hy the time hopping code determine the amplitude of the discret

[Program doc] noTHtransmitPAM

Description: 此函数用于产生脉冲超宽带系统的训练序列的波形。输出参数有三个：bits--发送的数据,stx--发送的信号,ref--参考信号 发送端调制方式为TH-PAM-The emerging ultra-wideband (UWB) system offers a great potential for high data rate wireless multimedia applications of the home entertainment and industry, as well as for low data rate sensor networks involving low power devices~\cite{paragraph1}. One of the most acute challenges in realizing these potentials of the UWB systems is the timing acquisition. Timing errors as small as fractions of a nanosecond could seriously degrade the system performance~\cite{paragraph21}. The difficulty in UWB synchronization arises from UWB signals being the ultrashort low-duty-cycle pulses operating at very low power density.

[Other] Blind-equalization

Description: 定义了一种余弦代价函数,提出了基于该代价函数的盲均衡新算法.该 余弦代价函数可将BPSK、M-PAM、M-QAM信号的不同星座点映射至原点,从而使新算法在对上述常模或非常模信号进行均衡时稳态均方误差均能收敛至零,更重要的是新算法能够在多径衰落环境下实现对上述信号的调制识别.理论分析和仿真结果证明了新算法的优良性能. -Defines a cosine cost function, this paper puts forward a new blind equalization algorithm based on the cost function. The cosine cost function can be BPSK, M- PAM, M- QAM signal constellation points mapped to different origin, so that the new algorithm based on the norm or very model when the signal is balanced steady state mean square error can converge to zero, the more important is that the new algorithm can be implemented in a multipath fading environment on the signal modulation recognition. Theoretical analysis and simulation results prove the good performance of the new algorithm.
