发明名称 Multi-sequence fast slewing pseudorandom noise generator
摘要 Techniques for fast-slewing of multi-sequence based PN generators are disclosed. In one aspect, LFSR states and reference counter states are loaded into their corresponding components such that consistency among the states is maintained. In another aspect, various methods for determining LFSR states and counter values in response to a desired offset in a unique code are disclosed. Among these methods are matrix-multiplication of LFSR states and generation of advanced LFSR states through masking techniques. Other methods are also presented. These aspects have the benefit of decreasing slew time in an efficient manner, which translates to increased acquisition speed, faster finger lock on multi-path signals, increased data throughput, decreased power, and improved overall system capacity.
