| Summary: | In vehicular communication systems, Dedicated Short Range
Communication (DSRC) is said to provide fast communication and high security
between vehicles. Simultaneously, Long-Term Evolution (LTE) is used due to its
high bandwidth, low latency, and high spectrum efficiency. The DSRC and LTE
hybrid model has gained much attention as it is feasible and simpler in design
and deployment. In fact, multiple-input multiple-output (MIMO) systems have
been widely used in modern wireless communication systems to enhance data
throughput, reliability, and coverage. This paper proposes a MIMO LTE-DSRC
hybrid system using space-time frequency block codes (STFBC). This paper
focuses on the physical layer performance of the LTE-DSRC hybrid uplink
structure. The DSRC Orthogonal Frequency Division Multiplexing (OFDM)
transmitter and LTE Single Carrier Frequency Division Multiplexing (SCFDM)
receiver are used for the uplink transmission. A study on bit error rate (BER),
pairwise error probability (PEP), and channel-to-interference ratio (CIR) of
the 2x2 MIMO LTE-DSRC system is conducted. The numerical results show that this
proposed method improves the error rate performance with a gradual increase in
signal-to-noise ratio (SNR) compared to the baseline systems. |
