Patent abstract

Spread spectrum GMSK signals are presented. Transmission may involve obtaining a sequence of data symbols, obtaining a spread spectrum code comprising a sequence of spread spectrum chips, generating a sequence of pre-modulation chips by combining the sequence of data symbols with the spread spectrum chips, wherein for each data symbol, at least one of the pre-modulation chips is generated by taking into account at least the data symbol and at least one of the spread spectrum chips, performing Gaussian Minimum Shift Keying (GMSK) modulation using the sequence of pre-modulation chips to produce a spread spectrum GMSK signal, and transmitting the spread spectrum GMSK signal.
