sdrrx

Create receiver System object for USRP embedded series radio hardware

Description

example

rx = sdrrx(DeviceName) creates a receiver System object™ with default properties that receives data from the USRP™ embedded series radio hardware specified by DeviceName. The object receives data over a gigabit Ethernet network connection.

When you call the receiver System object, the object connects to the radio hardware. The object stays connected until you call the release function. For more information on how to use the object, see the documentation of the corresponding System object.

rx = sdrrx(DeviceName,Name,Value) specifies additional properties using one or more name-value pair arguments. Unspecified properties take default values.

Make sure your radio hardware is configured for host-radio communication by following the steps in Guided Host-Radio Hardware Setup.

Create a receiver System object for your radio hardware with the specified properties. Use a single channel.

rx = sdrrx('E3xx', ...
    'IPAddress','192.168.3.2', ...
    'CenterFrequency',2.2e9, ...
    'BasebandSampleRate',800e3, ...    
    'ChannelMapping',1)
rx = 
  comm.SDRRxE3xx with properties:

   Main
                DeviceName: 'E3xx'
                 IPAddress: '192.168.3.2'
           CenterFrequency: 2.2000e+09
                GainSource: 'AGC Slow Attack'
            ChannelMapping: 1
        BasebandSampleRate: 800000
            OutputDataType: 'int16'
           SamplesPerFrame: 20000
           EnableBurstMode: false
    ShowAdvancedProperties: false

Create a log for recording data.

Log = dsp.SignalSink;

Receive and validate data by using the receiver System object. Save valid data using the log.

for counter = 1:20
    [data,validData,overflow] = rx();
    if validData == 1 
        if overflow ~=1 % contiguous data
             Log(data);
        end
    else
        disp('Not valid data.');
    end
end 
## Establishing connection to hardware. This process can take several seconds.

Input Arguments

Name of USRP embedded series radio hardware, specified as 'E3xx'. You can interface with any of these radio hardware devices:

  • USRP E310

  • USRP E312

Data Types: char | string

Name-Value Pair Arguments

Specify optional comma-separated pairs of Name,Value arguments. Name is the argument name and Value is the corresponding value. Name must appear inside quotes. You can specify several name and value pair arguments in any order as Name1,Value1,...,NameN,ValueN.

Example: 'CenterFrequency',2.5e9

For a full list of property names and values, see the reference page of the corresponding receiver System object rx.
