| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This summary describes example GNU Radio implementations of Python code that uses the USRP Hardware Driver (UHD) to achieve time alignment and phase synchronization between multiple USRPs and daughter boards based on the USRP Hardware Driver and USRP Manual of the Ettus Research. The implementation examples are intended for use with the USRP N200 and X300 series in combination with the SBX or Basic TX/RX daughter board. Sample codes for (a) simultaneous transmit and receive with one USRP, (b) simultaneous phase-aligned receive with two USRPs, and (c) simultaneous transmit and receive with two USRPs are shown as typical examples. This method achieves its goal by specifying the UHD property values, which are not assigned by the GNU Radio Companion (GRC), by using of the UHD Timed Commands. An own processing block for the GRC is developed. It enables the UHD Timed Commands extension on the GRC. | |
