The IEEE 802.11n is a high throughput (HT) wireless LAN standard that supports multiple input, multiple output orthogonal frequency division multiplexing (MIMO-OFDM) technology with maximum of 4 transmitting and 4 receiving antennas. This technology has been extended to 8 transmitting and 8 receiving antennas in upcoming very high throughput (VHT) wireless LAN standard, IEEE 802.11ac. Spatial expansion (SE) is a transmit diversity scheme used to map fewer space time streams to more transmit… CONTINUE READING
