| [[backend_uhd]] |
| === `osmo-trx-uhd` for UHD based Transceivers |
| |
| This OsmoTRX model uses _libuhd_ (UHD, USRP Hardware Driver) to drive the |
| device, that is configuring it and reading/writing samples from/to it. |
| |
| So far, this backend has been mostly used to drive devices such as the Ettus |
| B200 family and Fairwaves UmTRX family, and used to be the default backend used |
| for legacy @osmo-trx@ binary when per-backend binaries didn't exist yet. |
| |
| Any device providing generic support for UHD should theoretically be able to be |
| run through this backend without much effort, but pracitcal experience showed |
| that some devices don't play well with it, such as the LimeSDR family of |
| devices, which showed far better results when using its native interface. |
| |
| Related code can be found in the _Transceiver52M/device/uhd/_ directory in |
| _osmo-trx.git_. |
| |
| [[backend_lms]] |
| === `osmo-trx-lms` for LimeSuite based Transceivers |
| |
| This OsmoTRX model uses LimeSuite API and library to drive the device, that is |
| configuring it and reading/writing samples from/to it. |
| |
| This backend was developed in order to be used together with LimeSDR-USB and |
| LimeSDR-mini devices, due to to the poor results obtained with the UHD backend, |
| and to simplify the stack. |
| |
| Related code can be found in the _Transceiver52M/device/lms/_ directory in |
| _osmo-trx.git_. |
| |
| [[backend_usrp1]] |
| === `osmo-trx-usrp1` for libusrp based Transceivers |
| |
| This OsmoTRX model uses the legacy libusrp driver provided in GNU Radio 3.4.2. |
| |
| As this code was dropped from GNU Radio at some point and was found very |
| difficult to build, some work was done to create a standalone libusrp which can |
| be nowadays found as a separate git repository together with other osmocom git |
| repositories, in https://git.osmocom.org/libusrp/ |
| |
| Related code can be found in the _Transceiver52M/device/usrp1/_ directory in |
| _osmo-trx.git_. |
