hilbert
说明: 产生正弦信号时域波形及频谱,并通过希尔伯特滤波器。其中希尔伯特滤波器有两种产生方式,一是使用MATLAB自带的FDAtool;二是程序编写。(The time-domain waveform and spectrum of sinusoidal signal are generated and passed through Hilbert filter. There are two ways to generate Hilbert filter, one is to use FDAtool in MATLAB, the other is to write programs.)

extended_reciever
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.

Multiple input multiple output techniques combined
with orthogonal frequency division multiplexing (MIMO-OFDM)
provide a promising approach for wireless systems. However, a
serious drawback of the OFDM system is the high peak-toaverage
power ratio (PAPR), which may severely affect the
power efficiency of RF power amplifiers. In this paper, we
propose a simple method to reduce the PAPR of MIMO-OFDM
signals based on the use of unused subcarriers. Instead of
processing the signals at each transmitter separately, a peak
cancelling signal is generated at one antenna and is then applied
to all the others with only simple modifications. Simulation has
shown that a minimum 2 dB reduction in PAPR can be achieved
for all transmit signals using this approach. As the signal
processing is nearly all done at a single transmitter, repetition of
the operations at each transmitter is avoided, and therefore the
overall cost of the system can be significantly reduced.
