摘要： This disclosure involves methods and systems for compensating for imbalanced transmit antenna gains. A transmit controller independently samples the received signal in each chain of a transceiver selectively adjusts the transmit power at each antenna to minimize any indicated imbalance to improve performance at the node receiving the transmission.

摘要： A method and system of optimizing transmit beam forming in a multiple radio wireless system is provided. A stimulus signal can be provided to an analog receive input of a device under test (DUT), wherein the DUT includes multiple radios. A receive phase and amplitude can be measured at baseband using the stimulus signal for each radio. At this point, a receive weight and its conjugate can be determined using the receive phases and amplitudes. A calibration vector and its conjugate can also be determined, wherein a product of the receive weight conjugate and the calibration vector conjugate generate a transmit weight. This transmit weight can be applied to transmit signals during the transmit beam forming using the multiple radios.

摘要： A transmitter can send frames with a range of transmitter powers to another device in a wireless network. The quality metrics computed from these frames can be advantageously used to determine an optimal transmit power. These quality metrics can be computed by the other device or by the transmitter. Each quality metric can include an EVM and, optionally, also an RSSI. The transmitter can calibrate its optimal transmit power using the quality metrics. The optimal transmit power can be a maximum power that meets a minimum quality specification for a given supported modulation format, the transmit power that allows for a greatest path loss while maintaining a given packet error rate (PER), or the transmit power that maximizes a throughput supported in the wireless network.
