代码说明:

  Spread spectrum techniques can be very useful to overcome the communication problems like security and efficient usage of power. In this technique, the information signal to be transmitted is multiplied by the PN code (This is the general case and it can be any kind of sequence.),called spreading code signal. The signal which is obtained after the multiplication of PN code is called spread signal which is then transmitted.

  • jianju
    如果阵元间距小于半波长,则阵元间会产生耦合。如果阵元间距大于半波长,则阵列上会现多余的旁瓣,从而降低天线阵列的性能。而当阵列间距选取为半波长时,所估测出的效果最优。(If the array element spacing is less than half wavelength, it will produce coupling between array elements. If the array element spacing is greater than half wavelength, the array will now be extra sidelobes, thus reducing the performance of the antenna array. When the array spacing is half wavelength selection, the best estimate the effect.)
