Abstract: A method and system of symbol measurement and combining (SMaC) provides near-optimal performance for each user independently by relying on rapid digital beamforming with near-ideal convergence properties. This approach is also provides near-ideal performance without any knowledge of user/jammer location and adapts instantly as those locations change. An iterative joint estimation method is used to determine a covariance matrix RXX, and a user beamsteering vector, ?.

Abstract: During an exchange of communications between a client and a server, the state of communications is monitored to determine if the client has lost communication with the server prior to completion of the exchange. If a loss of communication is detected, a recovery message is transmitted to the client, wherein the recovery message is received by the client after client communications with the network are re-established. The recovery message causes the client to send a response message to a predetermined network location. Receipt of the response message is an indication that the client has re-established communication. In such a case, the exchange is returned to a state that existed prior to the loss of communication.
