Patent ID: 7817708

Claim:
An Orthogonal Code Division Multiplexing CCK (OCDM-CCK) wireless transceiver system, the system comprising: a RF (Radio Frequency) DSSS (Direct Sequence Spread Spectrum) transmission means for transmitting simultaneously a plurality of data carrying symbols, using a Complementary Code Keying (CCK) scheme, and means including: a serial-to-parallel data converter to convert a serial digital data input to a plurality of parallel data segments; an encoder to encode the said parallel data segments into a plurality of symbols in parallel baseband paths according to a Complementary Code Keying (CCK) scheme; a modulator to modulate the said data segments on distinct orthogonal and/or near-orthogonal CCK coded signals; and a summing circuit to sum the said CCK coded signals at baseband frequency to result in a composite signal; and a RF modulator to modulate the said composite signal on an RF carrier to transmit via a channel to a corresponding OCDM-CCK receiver.
