    波束形成就是从传感器阵列重构源信号。(1)、通过增加期望信源的贡献来实现;(2)、通过抑制掉干扰源来实现。经典的波束形成需要观测方向(期望信源的方向)的知识。盲波束形成试图在没有期望信源方向信息的情况下进行信源的恢复。 波束形成技术的基本思想是:通过将各阵元输出进行加权求和,在一时间内将天线阵列波束“导向”到一个方向上,对期望信号得到最大输出功率的导向位置即给出DOA估计。 虽然阵列天线的方向图是全方向的,但阵列的输出经过加权求和后,却可以被调整到阵列接收的方向增益聚集在一个方向上,相当于形成了一个”波束”。这就是波束形成的物理意义所在。 ()

  • HARQ
    利用matlab仿真了改进的二类选择重传HARQ机制的吞吐量与误比特率之间的关系。在仿真中对于编码和解码过程进行了简化:根据误比特率按概率模拟传输过程中码字的出错位数,在接收端只判断码字错误的位数是否在可纠错得范围之内。每发送一个码字,接收端根据出错位数信息检验其是否出错,没有出错则接收,否则要求重发,程序中利用alternate值交替发送信息码字和校验码字。当校验码字到来后,若校验码与原码组成的新码字能够纠错,则正确接收,否则要求重传。 (Retransmission the HARQ mechanism of throughput and bit error rate of the relationship between the use of matlab simulation improved second-class choice. In the simulation for the encoding and decoding process is simplified: digit of the code word of the error probability analog transmission process, according to the bit error rate of the receiving end only to determine the range of code word errors median whether error correction was. Each sending a code word, the information of the receiving end according to the error median test whether error, no error is received, or request retransmission, and the program using the alternate value alternately sent the information code word and the parity check code word. When the checksum word comes, if the new codeword able to check code with the original code error correction correctly received, otherwise require retransmission.)
