Abstract

A concatenated code combining an low-density parity-check (LDPC) code with a Reed-Solomon (RS) code, is designed based on the software-defined radio platform formed by universal software radio peripheral (USRP), which has compatible parameters with digital video broadcasting-terrestrial (DVB-T). Compared with the concatenated code combining a convolutional code with an RS code in DVB-T, the designed concatenated code obtains excellent error-correction performance, since LDPC performs better than the convolutional code, and the RS code can further eliminate error floor of the LDPC code. The designed code is implemented on a USRP platform. Its performance is tested in a wireless channel. The results show that high performance gain can be achieved by using the designed concatenated code as compared with the concatenated code in DVB-T.

Key words： concatenated code; convolutional code; software-defined radio; low-density parity-check (LDPC) code
