[USRP-users] Overflow with B210 for 2by2 MIMO design

Trying to develop 802.11n (a 2 by 2 MIMO) standard by using two B210s. Initially started with the existing flow of GnuRadio/examples/digital/OFDM/tx.ofdm.grc. Lets take only the transmitter side for this question. Things that are changed in OFDM.grc: 1. The OFDM allocator block: The sync

[USRP-users] Alternate transmission of frames on 2 TX USRP port

Hi, USRP UHD B210 – GnuRadio 3.7.10 I am generating frames and transmitting by using OFDM_tx example. Now I want to use 1 USRP sink (with 2 Tx port). And want every alternate packet from each sink. Example : Frame 1 (every odd number of frame) – USRP tx port 1 Frame 2 (every even number of

[USRP-users] Toggle between 2 transmit antennas

Hello All, I am using a USRP sink with 2 input channels on 2 TX/RX ports of B210 for transmitting a file. Now I want to toggle (or ON/OFF) between these transmission ports. For example: Ant-1 : Transmit for 1 msec and stop Ant-2 : Transmit for 1 msec and stop And again Ant-1….(loop until a

[USRP-users] How to separate "ofdm_sync_chan_taps" values for each antenna (2x2 config) MIMO.

Hello All, I am trying to build OFDM_MIMO (2 x 2). I have used the blocks from OFDM example folders and joined tx & rx together and transmitting/receiving over USRP B210. My aim is to get a channel state information (CSI). For that I have connected TAG DEBUG with OFDM CHANNEL ESTIMATION block
