Embodiment 1
[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0022] see figure 1 , which is a flow chart of a WLAN antenna combination method according to the present invention. A WLAN antenna combination method, comprising steps:
[0023] S10: Assign antenna weights to the switch states of each antenna, form an antenna weight sequence according to the antenna selection, and select multiple antenna weight sequences to form a contemporary antenna weight set suitable for genetic algorithm operations;
[0024] S20: pair-cross the antenna weight sequences in the contemporary antenna weight set according to the crossover probability, and mutate each antenna weight sequence in the crossover result according to the mutation probability to obtain a mutated antenna weight set;
[0025] S30: Calculate the fitness value f of each an...
Embodiment 2
[0089] see Figure 6 , which is a schematic diagram of a connection relationship between an antenna and a radio frequency stream in another embodiment of a WLAN antenna combination method according to the present invention. The general steps of this embodiment are the same as those of Embodiment 1, and the difference is that in this embodiment, radio frequency stream 1, radio frequency stream 2, and radio frequency stream 3 can establish connection relationships with antenna 1 to antenna 8 respectively. However, only one antenna can be selected for each radio frequency stream to establish a connection relationship. So there are 8.7.6 = 336 possible antenna combinations. All possibilities can be covered by 9-bit binary code. Therefore, in this embodiment, the antenna weight sequence is composed of 9 binary numbers. Since the 9-digit binary number can represent a total of 512 possible combinations, which is greater than the number of antenna combinations that can actually app...
