Abstract
Using a statistics-based assumption that a defective user device and a non-defective user device are not likely to transmit upstream data bursts during a given S-CDMA frame, a bad-burst count is incremented for each of a plurality of user devices that transmit an upstream burst during a frame when all bursts in the frame are deemed corrupt. If a given user device transmits an upstream burst in a frame having some non-corrupt bursts, the counter for that user device is cleared. When the count for any given device exceeds an associated predetermined threshold, that device is denied access to network resources so that performance of other properly performing devices is not degraded. Defective devices are identified to maintenance personnel for repair or replacement, and/or a defective device message can be sent downstream to the user device to alert the user that the device may need repair or replacement.
