B.3.1 3.84 Mcps TDD Option


B.3.2 1.28 Mcps TDD Option

MIMO propagation conditions are defined for a 2×2 antenna configuration. The resulting propagation channel shall be characterized by a complex 2×2 matrix termed

B.3.2.1 MIMO Dual Stream Static Orthogonal Conditions

The channel coefficients of the resulting propagation channnel under MIMO dual stream conditions shall be given by

The generation of the resulting channel coefficients for MIMO dual stream conditions and the association with the transmitter and receiver ports are depicted Figure B.1. Figure B.1 does not restrict test system implementation.
