From 7fad896c07fbdda4cf112e9e4999a5ab8f5484a5 Mon Sep 17 00:00:00 2001 From: Ashish Chaudhari Date: Sun, 13 Mar 2016 18:30:21 -0700 Subject: usrp3: Added RX DSP support for heterodyne sampling - rx_dsp_core: set_mux takes in a fe_connection obj to determine IQ mapping and sampling mode parameters - rx_dsp_core: Support a non-zero IF for downconversion The current strategy applies a software DSP freq offset which eats into the range of the CORDIC which is OK because heterodyne assumes real-mode sampling --- host/lib/usrp/e300/e300_io_impl.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'host/lib/usrp/e300') diff --git a/host/lib/usrp/e300/e300_io_impl.cpp b/host/lib/usrp/e300/e300_io_impl.cpp index f9ca7b0b2..c84042e98 100644 --- a/host/lib/usrp/e300/e300_io_impl.cpp +++ b/host/lib/usrp/e300/e300_io_impl.cpp @@ -157,7 +157,7 @@ void e300_impl::_update_subdev_spec( const std::string conn = _tree->access( mb_path / "dboards" / spec[i].db_name / ("rx_frontends") / spec[i].sd_name / "connection").get(); - _radio_perifs[i].ddc->set_mux(conn); + _radio_perifs[i].ddc->set_mux(usrp::fe_connection_t(conn)); _radio_perifs[i].rx_fe->set_mux(false); } } -- cgit v1.2.3
