    • Aspects of a method and system for a wireless integrated power test and measurement are provided. In this regard, concurrently with receiving a first signal via a first antenna, a second signal that indicates received signal strength of the first signal may be generated and transmitted via a second antenna. The second signal may be utilized to determine performance of the first antenna. A frequency of the generated second signal may be controlled so as to mitigate interference between the transmitted second signal and the received first signal. The first signal may be formatted in accordance with one or more first wireless standards and the second signal may be formatted in accordance with one or more second wireless standards. The received signal strength of the first signal may be determined via an analog-to-digital converter and the second signal may be updated at the sample rate of the analog-to-digital converter.

    • Space-Time-State Block Coded MIMO communication system using reconfigurable antennas. One or more antennas are operates in accordance with a Space-Time-State Block Code (STS-BC) to effectuate channel coding of a signal being transmitted wirelessly between communication devices. In accordance with such an STS-BC, one or more antennas (being reconfigurable in nature) of a communication device are reconfigured in different radiation states. From some perspectives, this may be viewed as performing three-dimensional channel coding, in that, in addition to achieving at least time diversity of signals being transmitted (and also potentially including spatial diversity), state diversity may be achieved by adapting one or more characteristics of one or more antennas within the communication device. Such an STS-BC may operate in an open loop configuration without requiring any feedback from another communication device to which signals are transmitted. If desired, feedback may be employed for adaptively modifying an STS-BC (or selecting another STS-BC).
