摘要：
This paper presents the results for the US Naval Research Laboratory developed digital VHF/UHF antenna selector out-of-tree module developed for use in GNURadio. Testing was performed at NRL in August 2018. The results for the test show that the antenna selector successfully switched the input signal during reception without loss of the voice/radio signal. The switching was performed with each call to the out of tree module and would switch all samples for that specific call from the best antenna input to the output. The module was optimized using calls to memcpy to ensure no loss in performance due to loops. The input signal power computation was computed using the built-in FFTW library and additional function calls.
