This program simulates the bit-error-rate (BER) performance of OSTBC
with L=4 antennas over the frequency flat Rayleigh block fading channel
The code is developed for real orthogonal design, code rate 1/2
modulation- 16 QAM with gray coding resulting in 2 bits/sec/Hz.

This is GPS Matlab findPreambles finds the first preamble occurrence in the bit stream of
each channel. The preamble is verified by check of the spacing between
preambles [6sec] and parity checking of the first two words in a
subframe. At the same time function returns list of channels, that a ...

This will sample all 8 A/D-channels by the continous mode.
Each end of conversion will call an interrupt routine,
where the AD-channel is put to Port4[2..0]
and the upper nibble of the result is put to Port4[7..4].
Port 4 is connected to the user LEDs of the FlashCan100P Evaluation-Board

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.

技术资料 模拟电路工程师的三大法宝
为了提高单根线的传输速率，必须要讲到我们模拟电路工程师的三大法宝，差分信号（differential signaling），时钟-数据恢复（Clock-Data Recovery，简称 CDR），和信道均一化（Channel Equalization，Eq）。
技术资料 单载波MIMO 系统的一种抑制噪声的MMSE信道估计方案
单载波MIMO 系统的频域均衡是对抗信道频率选择性衰落的有效方法，它的良好性能依赖于接收端准确的信道估计(Channel Estimation,CE)。常见的迫零信道估计(ZF-CE)在导频频
