    MIMO Fundamentals Antenna Configurations

    Leading the MIMO Revolution

    MIMO Fundamentals

    Traditional systems use a 2 dimensional signaling space: Time and Frequency

    MIMO systems enable the transmission of multiple signals at the same time and frequency by exploiting a 3rd dimension: Space

    Compared to SISO, MIMO provided several benefits: Higher data throughput

    Improved range and robustness

    Lower output power for a given distance

    User can trade between these to achieve project goals

    MIMO Techniques Spatial Multiplexing

    Transmit a different data-set (stream) from each antenna

    All streams operate at the same frequency, mixing within the RF channel

    Sophisticated signal processing allows each individual stream to be recovered at the receiver

    Provides dramatic increase in throughput for a given channel size (higher data rates)

    Leading the MIMO Revolution

    MIMO Techniques Space Time Coding (STC)

    Transmit redundant, robustly-coded copies of data from all antennas Coded in time to avoid time-specific signal interruptions

    Coded in space by sending data over multiple signal paths

    Sophisticated signal processing allows data to be recovered at receiver

    Enables higher probability of successful data transmission in all environments (improved robustness)
