Patent ID: RE40231

Claim:
A spread spectrum radio transceiver comprising: a baseband processor and a radio circuit connected thereto, said baseband processor comprising a demodulator for spread spectrum phase shift keying (PSK) demodulating information received from said radio circuit, at least one analog-to-digital (A/D) converter having an output connected to said demodulator and an input AC-coupled to said radio circuit, said demodulator comprising at least one modified Walsh code function correlator for decoding information according to a modified Walsh code having a reduced DC component for reducing an average DC signal component which of the information decoded by the modified Walsh code relative to that information being decoded by an unmodified Walsh code which, in combination with the AC-coupling to said at least one A/D converter enhances overall performance, and a modulator for spread spectrum PSK modulating information for transmission via the radio circuit, said modulator comprising at least one modified Walsh code function encoder for encoding information according to the modified Walsh code.
