OFDM MIMO Info (Custom OFDM)

The OFDM MIMO Info table shows a MIMO Multiple Input, Multiple Output: A physical layer (PHY) configuration in which both transmitter and receiver use multiple antennas. measurement's power per RU RU is an abbreviation for Resource Unit, where one resource unit is a single subcarrier at a single symbol time. The value displayed is the total number of resource units occupied by subcarriers of the specified Resource Type., phase offset and TAE for each antenna port.

OFDM Orthogonal Frequency Division Multiplexing: OFDM employs multiple overlapping radio frequency carriers, each operating at a carefully chosen frequency that is Orthogonal to the others, to produce a transmission scheme that supports higher bit rates due to parallel channel operation. OFDM is an alternative tranmission scheme to DSSS and FHSS. MIMO Info is a type of Matrix Table that provides sortable rows by column, selectable column visibility, and copy/paste and export functionality to share rows of content or complete tables to applications like email, text editing or spreadsheet programs.


Portn	Chn	Power is the per-RU power at each antenna port of the MIMO measurement.	Phase Offset is the detected phase offset of the physical channel for each path, relative to the reference path (Phase Offset = 0). The reference path is decided by the Synchronization Antenna Port and Synchronization Channel Index parameters.	TAE (Time Alignment Error) is the detected timing offset of the physical channel for each path, relative to the reference path (TAE = 0). The reference path is decided by the Synchronization Antenna Port and Synchronization Channel Index parameters.

Power is the per-RU power at each antenna port of the MIMO measurement.

Phase Offset is the detected phase offset of the physical channel for each path, relative to the reference path (Phase Offset = 0). The reference path is decided by the Synchronization Antenna Port and Synchronization Channel Index parameters.

TAE (Time Alignment Error) is the detected timing offset of the physical channel for each path, relative to the reference path (TAE = 0). The reference path is decided by the Synchronization Antenna Port and Synchronization Channel Index parameters.

n denotes the physical channel, measurement channel, user or antenna port number.

Averaging is not applied to the OFDM MIMO Info trace.
