Orthogonal Code Hopping Multiplexing for Downlink in Spread Spectrum Communications
A statistical multiplexing scheme in orthogonal downlinks is proposed to accommodate more downlink orthogonal channels than orthogonal codewords for mobile stations. The number of allocable downlink orthogonal channels depends on the average burstiness of the channels. The statistical multiplexing scheme is called here as the orthogonal code hopping multiplexing (OCHM). Since the OCHM uses a pr...
متن کاملCDMA(Code Division Multiplexing Access)
Multiple users can be served by the same bandwidth in wireless CDMA systems of spread spectrum. The use can used the bandwidth and different codes at the same time and any signal showed by one of the user is seen as interference. This interference is detected to the base station in the process of extracting data used by a specific signal utilized by a user. Users who are closer to the BS are th...

متن کاملSpread Spectrum Code Estimation by Genetic Algorithm
In the context of spectrum surveillance, a method to recover the code of spread spectrum signal is presented, whereas the receiver has no knowledge of the transmitter’s spreading sequence. The approach is based on a genetic algorithm (GA), which is forced to model the received signal. Genetic algorithms (GAs) are well known for their robustness in solving complex optimization problems. Experime...
