Q:

_______ is an additional open-loop MIMO technique considered by the WiMAX vendors.

A) STTD B) SM
C) Collaborative Uplink MIMO D) MU-MIMO
 
Answer & Explanation Answer: C) Collaborative Uplink MIMO

Explanation: Collaborative MIMO is an open-loop MIMO technique considered by the WiMAX vendors to surge the spectral efficiency and capacity of the uplink communications path. It is compared with the regular spatial multiplexing, wherein data streams are transmitted multiplying from multiple antennas on the same device.

Q:

MIMO means both transmitter and receiver have multiple antennas.

A) True B) False
 
Answer & Explanation Answer: A) True

Explanation: MIMO provides a way of utilising the multiple signal paths that exist between a transmitter and receiver to significantly improve the data throughput available on a given channel with its defined bandwidth. It uses multiple antennas at the transmitter and receiver along with some complex digital signal processing.
