摘要： The absolute total isotropic sensitivity is determined for a communication device receiver circuit that is within a scattered field chamber (SFC) and is receiving communications from a base station simulator. Movement of a mode stirrer device within the SFC is controlled to sequentially move the mode stirrer device to a plurality of different static positions. The different static positions of the mode stirrer device are configured to differently mix polarizations of incident RF fields in the SFC. At each of a plurality of the different static positions of the mode stirrer device, the transmission power level from the base station simulator is varied through a plurality of different transmission power levels. At each of a plurality of the transmission power levels, a bit error rate and a received signal strength at which the communication device receives the communications from the base station simulator are measured. The absolute total isotropic sensitivity of the communication device receiver circuit is determined in response to the measured bit error rate, the measured received signal strength, and the associated transmission power levels.

摘要： A system and method for low complexity frequency hopping simulation for communication device performance testing is disclosed. A baseband and channel model combination in a baseband processing module (602) of a testing system (600) reduces the required number of computations while retaining accuracy. A simulated channel is generated (612) with a bandwidth required for frequency hopping, and the hopping is simulated by shifting (614) the channel (612) instead of the signal (606). Signal attenuation by the shifted channel (615) is modeled in the baseband processing module (602), and the resulting simulated signal (610) is then up-sampled (628) to the proper frequency for output to the test device (634).

摘要： A methodology of signal estimation over the generalized fading channel can be applied to any parameter whose dB value is required to be estimated. The estimator is shown to be asymptotically efficient in a number of samples and the amount of fading. Theoretical and simulation results confirm that the SINR estimator implemented using the methodology outperforms the sample-average estimator, which is currently used in most of systems and robust to the channel variation.

摘要： Link performance is measured in a code division multiple access (CDMA) personal communication service (PCS) or cellular system, or other type of wireless system, using a test set-up which permits the simulation of various changes in system configuration. An illustrative embodiment includes a first attenuator arranged in a common portion of a receive path and a transmit path of a mobile station of the system, and a second attenuator arranged in either a receive-only portion of the receive path or a transmit-only portion of the transmit path. The amounts of attenuation provided by the first and second attenuators are decoupled such that a different amount of attenuation can be provided on the transmit path than on the receive path. Performance of forward and reverse links of the system are measured while varying a value of at least one of the first or second attenuators. For a given measurement, the attenuator values may be selected to simulate performance of the system in a configuration in which base station amplifier power is increased or decreased. As another example, the attenuator values may be selected to simulate performance of the system in a configuration in which cell size is increased. This arrangement of decoupled forward and reverse link attenuation in accordance with the invention permits efficient and accurate determination of link balance conditions.

摘要： For determining the spatial distribution of the traffic volume within a radio cell of a cellular mobile radio communications network, a test signal transmitter is usually installed at a test location. Each mobile station which receives the test signal, measures and reports the receive level to a computer for evaluating the test location. The test location is deemed to be suitable for the installation of a new base station if the majority of the mobile stations receives a test signal of sufficient strength. In order to provide a simple method for determining the spatial distribution, it is proposed to first subdivide the radio cell (RC1) into several segments or sections (A1, A2, A3, . . . , D4) and to associated respective reference values (e.g. reference receive levels) with these segments or sections. The reference values are calculated with the help of a Radio Communications Network Planning Tool, wherein the distances from the segment or section (C2) to at least two of the base stations (BS1, BS2) can be derived from the reference values. Subsequently, measured values (e.g. the actual receive level) which depend on the length of the radio transmission paths, are determined for each mobile station (MS). After the reference values are compared with the actual values, the respective segment or section (C2) in which the mobile station (MS) is currently located, is determined. A counter state indicating the traffic volume in this segment or section (C2) is then incremented for this segment (C2). A test signal transmitter is not required, because that section (C2) of the cell which has the highest count state, representing the highest traffic volume, has been shown to be a desirable location for a reliever base station, without having to put a test transmitter there.
摘要翻译：为了确定蜂窝移动无线电通信网络的无线电小区内的业务量的空间分布，测试信号发射机通常安装在测试位置。接收测试信号的每个移动台测量并报告计算机的接收电平以评估测试位置。如果大多数移动台接收到足够强度的测试信号，则该测试位置被认为适于安装新的基站。为了提供用于确定空间分布的简单方法，建议首先将无线电小区（RC1）细分成若干段或部分（A1，A2，A3，...，D4）并将其相关联的相应参考值例如参考接收级别）与这些段或段。借助于无线电通信网络规划工具来计算参考值，其中可以从参考值导出从段或段（C2）到至少两个基站（BS1，BS2）的距离。随后，针对每个移动台（MS）确定取决于无线电传输路径的长度的测量值（例如，实际接收电平）。在将参考值与实际值进行比较之后，确定移动台（MS）当前所在的相应段或部分（C2）。然后，指示该段或段（C2）中的业务量的计数器状态对于该段（C2）而增加。不需要测试信号发射机，因为具有最高计数状态的单元的部分（C2）代表最大的业务量，已被证明是缓解基站的理想位置，而不必进行测试发射机在那里
