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MIMO分组的传输完成之前通过发送在MIMO分组上“踩踏”。 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。

Abstract: A satellite navigation receiver having a digital front end. The satellite navigation receiver includes an analog section for receiving, amplifying, and filtering a satellite navigation signal. The digital front end is coupled to the analog section and is used to perform digital signal processing on the satellite navigation signal before it is passed on to the acquisition and tracking engines. By off-loading some of the functionality from the analog section to the digital front end, the analog section may be made smaller and cheaper and may consume less power. Moreover, additional functionalities can be added to the digital front end to improve performance. Since the digital front end is comprised of digital circuitry, it scales down in size, cost, and power with advances in semiconductor fabrication techniques.
