说明：  实现ldpc的编译码功能，译码算法使用的对数域bp译码算法(LDPC codec realize the function of decoding algorithm used in log-domain decoding algorithm bp)

几个关于MIMO雷达的仿真程序，对学习相关内容的人有些帮助。(Several of the simulation program about MIMO radar to the study of relevant content people some help.)

此代码为MIMO-OFDM源程序，包括PSK调制与解调，空时分组编译码，信道建模等部分(This code for MIMO-OFDM source, including PSK modulation and demodulation, space-time block coding and decoding, channel modeling and other parts)

是用于OFDM系统， 能有效地降低系统地PAPR，同时可利用伪随机序列来结合PTS减少计算地复杂性和冗余(Be suitable for OFDM system to reduce the PAPR. and to combine with the m sequence to reduce the complexity of PTS algorithm.)

超宽带UWB,包括 uwb mdl UWB model - open this to begin uwb_lib mdl Libr()

在实际的调谐解调电路中，采用的是非相干载波解调，本振信号与发射端的载波信号存在频率偏差和相位抖动，因而解调出来的模拟I、Q基带信号是带有载波误差的信号。这样的模拟基带信号即使采用定时准确的时钟进行取样判决，得到的数字信号也不是原来发射端的调制信号，误差的积累将导致抽样判决后的误码率增大，因此数字QPSK解调电路要对载波误差进行补偿，减少非相干载波解调带来的影响。(In the actual tuning and demodulating circuit, non-coherent carrier demodulation is adopted, and the frequency deviation and phase jitter of the local oscillator signal and the carrier signal of the transmitting end are present, and thus the demodulated analog I and Q baseband signals are signals with carrier error.)

This paper presents a performance of the UWB system in a time hopping binary pulse position ultra-wideband modulation scheme (TH BPPM-UWB) in the presence of an AWGN channel.
