Their errors have to be reduced to obtain efficient Bit Error rate (BER). Over unreliable or noisy communication channels, errors in data can be controlled effectively using Error-correcting Code (ECC). NI USRP (National Instruments Universal Software Radio Hardware) 2954R support 5G with multiradio cooperation using Multiple- Input, Multiple Output (MIMO) techniques. The frequency of NI USRP 2954R ranges from 10 MHz to 6GHz with 160MHz bandwidth. In a software radio by mean of software upgrade a new technology can be easily implemented whereas the functionality is defined in software itself. Thus, in 4G communication, a forward error correction code (FEC) like LDPC is used. In this paper LDPC codes with Binary Phase Shift Keying (BPSK) modulation is simulated with NI lab-view and the performance of the LDPC code for the dimension (100,50,3) is analyzed. The experimental results demonstrate that as a signal to noise ratio (SNR) increases, BER decreases.
