Hello! I am working on a testbed using a 2x8 antenna array base station and as UE I use the AD9361.
Both Bs and UE are using the same LTE_20 FIR configuration for the sample rate of 30.72 MHz.
My problem is that when I use the UE (2x2 transceiver called AD9361) as a single antenna (using one RF chain), the signal at the base station arrives half of the size that I am actually sending.
My question is, how do I have to re-design these filters in order to operate only one RF chain?
Thank you very much!
