Solutions for a Real Time World
The RTL8191SU-GR builds in an enhanced signal detector, an adaptive frequency domain equalizer,
and a soft-decision Viterbi decoder to alleviate severe multi-path effects and mutual interference in
the reception of multiple streams. For better detection quality, receive diversity with Maximal-Ratio-
Combine (MRC) applying up to two receive paths is implemented. Robust interference detection and
suppression are provided to protect against Bluetooth, cordless phone, and microwave oven
interference.
Receive vector diversity for multi-stream application is implemented for efficient utilization of the
MIMO channel. Efficient IQ-imbalance, DC offset, phase noise, frequency offset, and timing offset
compensations are provided for the radio frequency front-end. Selectable digital transmit and receive
FIR filters are provided to meet transmit spectrum mask requirements and to reject adjacent channel
interference, respectively.
The RTL8191SU-GR supports fast receiver Automatic Gain Control (AGC) with synchronous and
asynchronous control loops among antennas, antenna diversity functions, and adaptive transmit
power control functions to obtain better performance in the analog portions of the transceiver.
The RTL8191SU-GR MAC supports 802.11e for multimedia applications, 802.11i for security, and
802.11n for enhanced MAC protocol efficiency. Using packet aggregation techniques such as A-MPDU
with BA and A-MSDU, protocol efficiency is significantly improved. Power saving mechanisms such as
U-APSD, APSD, and MIMO power saving reduces power wasted during idle time, and compensates
for the extra power required to transmit MIMO OFDM. The RTL8191SU-GR provides simple legacy
and 20MHz/40MHz co-existence mechanisms to ensure backward and network compatibility.
