Hi!

We are currently doing some experiments on LTEⁱ by using software defined radio. We write our program in CCS 5 and use the Spectrum Digital emulator to test the program.

The boards we are using have already integrated DSP, FPGA, and MCU. We want to send some particular data from eNodeBⁱ to UEⁱ to test the accuracy of the transmission. We know that the data should be carried in PDSCH. However, we do not know how the DSP can read the data that we define. We believe that FPGA is used for transmitting the data and MCU is used for controlling so DSP should read the user data from MCU. Our questions are as follows.

1.What can we do in order to let DSP read the specific data that we define from MCU?

2.We know that in LTE standard, the signal needs to go through some processes like CRC, coder, and modulation. In order to test the accuracy of the transmission, the data in which process should be compared in the transmitter and receiver?

Thanks very much!
