CONSTANT AMPLITUDE ENCODING METHOD FOR CODE DIVISION MULTIPLEX COMMUNICATION SYSTEM

摘要

PURPOSE: A constant amplitude encoding method for a code division multiplex communication system are provided to produce various diffusion gains and transmission rates by generating a constant amplitude signal instead of a multi amplitude signal. CONSTITUTION: The n bit code equal to an input signal is generated to encode a constant amplitude of a transmission signal(S10). The generated n bit code is diffused by applying an orthogonal codeword set(S20). The additional information is added to show the output characteristic of the constant amplitude(S30). The orthogonal codeword set structure is generated by using a walsh-hadamard matrix.
