Abstract: A multiple-input multiple-output (MIMO) system can transmit on multiple antennas simultaneously and receive on multiple antennas simultaneously. Unfortunately, because a legacy 802.11a/g device is not able to decode multiple data streams, such a legacy device may “stomp” on a MIMO packet by transmitting before the transmission of the MIMO packet is complete. Therefore, MIMO systems and methods are provided herein to allow legacy devices to decode the length of a MIMO packet and to restrain from transmitting during that period. These MIMO systems and methods are optimized for efficient transmission of MIMO packets.

Abstract translation: 多输入多输出（MIMO）系统可以同时在多个天线上进行发射并同时在多个天线上进行接收。 不幸的是，由于遗留802.11a / g设备不能解码多个数据流，所以这样的传统设备可能在完成MIMO分组的传输之前通过发送来“踩踏”MIMO分组。 因此，本文提供MIMO系统和方法，以允许传统设备对MIMO分组的长度进行解码并且在该时间段内抑制发射。 这些MIMO系统和方法被优化用于MIMO分组的有效传输。
