Methods and apparatus for compensation for corrupted user identification data in wireless networks

摘要

Methods and apparatus that correct for corrupted user identification or other data based on reciprocal transmission channel characteristic. In one embodiment, a level of tolerance is disclosed which provides a degree of leniency in user identification. In alternate embodiments, a level of tolerance is disclosed which provides a narrow window for "guessing" of user identification. Various methods for quantization and specification of tolerances are also disclosed. Methods and apparatus useful for implementing variation-tolerant encryption schemes are also provided.
