Abstract: A system and method are disclosed that may allow for enhanced gain control for two radios. In an example method, a first radio may receive a wireless signal on a first frequency band, the wireless signal including at least a header and a payload. A first gain control operation may be performed based at least in part on information in the header of the wireless signal. A second radio may be determined to initiate a transmission on a second frequency coinciding with the first frequency band before reception of the wireless signal is completed, where the second radio is co-located with the first radio. A second gain control operation may be performed based at least in part on an expected interference associated with the transmission from the second radio, and one or more gain levels may be adjusted for reception of the wireless signal, based on the second gain control operation.

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。

Abstract: A high sensitivity GPS receiver includes an acquisition engine and a tracking engine. The acquisition engine processes GPS satellite data at data rate that is substantially equal to twice the coarse acquisition (CA) code chip rate. This data rate advantageously enables the acquisition engine to process GPS satellite data with relatively less hardware area than traditional GPS acquisition approaches. In one embodiment, the high efficiency acquisition engine may be over-clocked, thereby allowing different phases of a CA code to be correlated quickly. The tracking engine can advantageously process GPS satellite data at a data rate that does not have an integer relationship to the CA code chip rate.
