A Novel Test Scheme for Crossly-polarized Electromagnetic Wave Based on Pseudo-random Codes

With the fast growth of 5G communication, researchers have paid a lot of attention to crossly-polarized scalable channels. However, microwave anechoic chamber is almost an indispensable condition to conduct the simulation test comparisons experiment currently. In the current simulation test comparisons, the advantages of applying cross polarization from the whole system’s point of view is rarely verified. Therefore, we propose a novel test scheme for crossly-polarized electromagnetic wave based on pseudo-random codes, which concludes a pseudorandom code generation algorithm based on parallel Hash function, which makes it possible to generate pseudo-random code of specific length and an inimitable structure effectively. Multiple actual measurements are conducted in indoor and outdoor environments, and we find the scheme presented in the paper can get satisfactory results without the environment of microwave anechoic chamber, which gives a solution to the traditional method’s voracious demand of microwave anechoic chamber.
