OFDM basic code with cp,ifft and fft,hope it willbe benefical for you to understand the OFDM basics

Photonic crystals are attractive optical materials for controlling and manipulating the flow of light. One dimensional photonic crystals are already in widespread use in the form of thin-film optics with applications ranging from low and high reflection coatings on lenses and mirrors to colour changing paints and inks. Higher dimensional photonic crystals are of great interest for both fundamental and applied research, and the two dimensional ones are beginning to find commercial applications. The first commercial products involving two-dimensionally periodic photonic crystals are already available in the form of photonic-crystal fibers, which use a microscale structure to confine light with radically different characteristics compared to conventional optical fiber for applications in nonlinear devices and guiding exotic wavelengths. The three-dimensional counterparts are still far from commercialization but may offer additional features such as optical nonlinearity require

主板故障的确定，一般通过逐步拔除或替换主板所连接的板卡（内存、显卡等），先排除这些配件可能出现的问题后就可以把目标锁定在主板上(Motherboard fault is fixed, or replace the motherboard through the gradual removal of the connected board (memory, graphics, etc.), first rule out possible problems of these accessories can be targeted after the motherboard)
