摘要：
A subscriber device (2) includes a long code generator (12) and a modifier (30) for generating a spread bit stream with a predetermined error pattern that is transmitted by a transmitter (16) at the subscriber device (2) to a base station (3). The base station (3) identifies the current subscriber device properties by identifying the error pattern and subsequently compares the current subscriber device properties with a knowledge base of subscriber device software properties associated with the error pattern in the spread bit stream. The knowledge base is stored in a memory source (4).
