Channel emulation for testing network resources

A device, comprising:

• a memory;
• and
• one or more processors to:
• receive, from the memory, fading channel conditions to utilize for simulating behavior of a plurality of mobile devices in a mobile network,
• at least one of the fading channel conditions for at least one of the plurality of mobile devices being different than at least another one of the fading channel conditions for at least another one of the plurality of mobile devices;
• generate channel realizations based on the fading channel conditions,
• the channel realizations including frequency-correlated, random channel coefficients;
• generate a test channel based on the generated channel realizations;
• and
• provide the test channel to a receiver device of the mobile network,
• the test channel causing the receiver device to process the test channel in a same manner the receiver device would process an actual channel.

A device, comprising:

• a buffer memory to store fading channel conditions associated with a mobile network;
• a channel emulator engine, at least partially implemented in hardware, to:
• receive selections of particular fading channel conditions to utilize for simulating behavior a plurality of mobile devices in the mobile network,
• at least one of the particular fading channel conditions for at least one of the plurality of mobile devices being different than at least another one of the particular fading channel conditions for at least another one of the plurality of mobile devices,
• retrieve the particular fading channel conditions from the buffer memory, and
• generate channel realizations based on the particular fading channel conditions,
• the channel realizations including frequency-correlated, random channel coefficients;
• a multiplier component and an adder component to:
• receive the channel realizations from the channel emulator engine, and
• generate a test channel based on the channel realizations;
• and
• an inverse fast Fourier transform component, at least partially implemented in hardware, to:
• receive the test channel from the adder component, and
• provide the test channel to a receiver device of the mobile network,
• the test channel causing the receiver device to perform functions associated with processing an actual channel.
