SISO and MIMO are abbreviations used in the field of telecommunications and wireless communication to describe different types of systems.

SISO: Single Input Single Output

SISO: SISO stands for “Single-Input Single-Output.” In a SISO system, there is a single input and a single output. This means that there is only one transmitter and one receiver involved in the communication link. The input signal is transmitted through a channel, and the output signal is received at the other end of the channel. SISO systems are commonly found in basic communication scenarios like traditional telephone lines or simple radio broadcast systems.

MIMO: Multiple Input Multiple Output

MIMO: MIMO stands for “Multiple-Input Multiple-Output.” In a MIMO system, there are multiple inputs and multiple outputs. This means that there are multiple transmitters and receivers involved in the communication link. The input signals are transmitted simultaneously using multiple antennas, and the output signals are received and processed by multiple antennas at the receiver end. MIMO technology is commonly used in modern wireless communication systems, such as Wi-Fi networks and cellular networks like 4G LTE and 5G. By utilizing multiple antennas, MIMO systems can improve data throughput, increase system capacity, enhance signal quality, and provide better resistance to fading and interference.

Summary SISO vs MIMO

In summary, SISO refers to a system with a single input and a single output, while MIMO refers to a system with multiple inputs and multiple outputs.
