Abstract

Performance analysis of antenna techniques on wireless communication systems was the focus of this work.
This was brought about as a result of the ever-increasing demand for higher communication channel capacity
and baud rates resulting from the global technological revolution informed by increased number of users.
Hence, there is urgent need to device technique(s) to effectively combat these and other related challenges.
Measurement data was sourced from one of the network service providers in Lagos, Nigeria. Four channel
capacity enhancement of transmission schemes: Single Input Single Output(SISO), Single Input Multiple
Output (SIMO), Multiple Input Single Output (MISO) and Multiple Input Multiple Output (MIMO) were
investigated. Their performances in terms of capacity and bit error rates at the receivers’ outputs were
compared using a binary phase shift keying for Rayleigh fading channel. The results showed that MIMO
antenna system have more capacity and higher reliability compared to other antenna systems. This is made
possible owing to the larger number of antennas in its design. Also, the BER values for the MIMO are much
lower than that of the other three antenna schemes, inferring better performances. Furthermore, better
performance is observed as the number of antenna configuration increases on MIMO. Again, as the number of
antennas at both ends increased, the channel capacity increased while the Bit Error Rate (BER) decreased,
leading to improved reliability over and above the use of a single antenna channel. The findings of this work
will be useful for network channel designers and mobile network service providers for 4G, 5G and Long Term
Evolution (LTE) systems
