Resumen

© 2017 IEEE. The legacy access networks should provide higher capacity, rate and spectral efficiency due to high demand of data transmission. In this context our proposal is the combining of LDPC codes with MIMO systems channels in order to improve the reliability and capacity in the transmission for massive connectivity. This system is proposed for the development of new technologies over SDR systems. MIMO techniques such as Alamouti-STBC offer some benefits such as greater network access capabilities that help to make transmission more reliable, while LDPC codes give higher transmission reliability because they have a good error correction codes and offer an approximation to the limit of capacity established by Shannon. The results show that the BER performance and the capacity improves when the Rayleigh channel is used. In this context, the system can support high quality of information and high rates in the transmission. In addition, we present the techniques of frame synchronization for real transmission as Barker codes, in order to reduce the error of transmission.
