Abstract: In this work, we present a novel receiving device design for communications systems that incorporates multiple antennas at the transmitting device/receiving device. Unlike existing systems, the new system does not require prior knowledge of the channel state information (CSI) at the receiving device side to extract the information symbols from the received signal. Consequently, complexity reduction and bit error rate improvement can be jointly achieved. Moreover, the new system may offer spectral efficiency enhancement since it does not require nulling to prevent the pilot symbols as in the case of conventional systems. The results obtained show that in certain scenarios the proposed system can offer up to 15 dB of bit error rate improvement over conventional systems. Moreover, the new system can provide about 16.6% of the spectral efficiency improvement.
