    摘要: A testing system comprises an emulator having a simulated radio channel for communicating therethrough with the electronic device. The testing system comprises a plurality of antenna elements coupled to an emulator which forms a beam of a signal of a path of a simulated radio channel with at least two antenna elements of the plurality of antenna elements in an anechoic chamber.

    摘要: A radio channel is formed for estimation, the radio channel including dominant paths from a digital impulse response estimate of a channel relating to a radio system. A divider divides the impulse response estimate temporally into at least two subsignals. An analyser determines whether a distribution of the amplitude values of at least one subsignal is gaussian or non-gaussian. A searcher searches for a highest amplitude value in each subsignal, which is determined to be non-gaussian. A generator may form a radio channel for a radio channel simulation, the radio channel including each propagation path corresponding to the highest amplitude value in each subsignal determined to be non-gaussian.

    摘要: A method and arrangement for generating data for transmitter or receiver simulations where the generated data includes Multiple Input Multiple Output radio environment (MIMO) characteristics. The arrangement includes a model data (11), which is off-line loadable to transmitter baseband unit (12). The model data is transmitted over a MIMO environment (14, 24), which scrambles the transmitted data. A receiver baseband unit (16) receives and saves the data. From the receiver baseband unit (16) the received data is loadable off-line to an external device where the data can be utilized in transmitter or receiver algorithm simulations.
