发明名称 System and method for determining path loss with hysteresis in a radio communication system
摘要 <p>A test method is for determining RF path loss between an RF source and an RF receiver. The RF source may transmit RF power values at a relatively fine granularity, and the RF receiver may generate RSSI values at a relatively coarse granularity and have an unknown hysteresis about each transition between adjacent RSSI values. Hysteresis edges may be determined about a given RSSI value transition at the RF receiver by sweeping RF power values transmitted from the RF source in increasing and decreasing directions. A relationship between the relatively fine granularity RF power values and the relative coarse granularity RSSI values may be determined using the hysteresis transition edges. The RF path loss for a given channel may be determined based upon a given RSSI at a given RF power value and the relationship between the relatively fine granularity RF power values and the relative coarse granularity RSSI values.</p>
