Maxfiner has worked in the wireless communication department of Huawei Communication Technology Co., Ltd., and has many years of experience in engineering project development. It also has algorithm theory research, simulation verification, and corresponding hardware design implementation capabilities. It has practical experience in all aspects of communication physical layer development and design. .
Convolution is a basic concept of signal processing. One of the most important aspects of its implementation is perhaps the following sentence: The convolution of the time domain corresponds to the multiplication of the frequency domain. In this sentence, or in other words, this concept will be fully reflected in many applications, such as frequency domain equalization, such as channel estimation, such as filtering analysis. The convolution formula, at first glance, seems a bit awkward. Why is this form, why is one of the signals to be flipped?
Through the above derivation, and then experience and observe the convolution formula, perhaps there is no such unintuitive feeling.

1. Desktop Mobile Phone Holder; open the Phone Holder directly to 45 degrees, put the phone on it and you can use it
2. The bedside mobile phone holder; fix the clip of the mobile phone holder on the side of the bed, freely adjust the bending degree of the holder and the position of the mobile phone according to your posture, which is convenient and more comfortable.
3. Stick to the wall mobile phone bracket; the bracket sticker has strong adhesiveness and can be fixed and hung on glass, ceramic tiles and painted walls.
4. Car phone holder; car air outlet bracket, fixing method: After the mobile phone is installed on the mobile phone bracket, pop out the steel piece in the middle of the mobile phone bracket and put it into the car air outlet to fix it
5. Ring buckle mobile phone holder, the usage method only needs to stick the suction ring on the back of the phone, and then put the ring out to place the phone.
