发明名称 System and method for receiving a multiple format wireless signal
摘要 An apparatus (200) and method (300) for receiving a communications signal. A spread spectrum signal demodulator (210) is adapted to demodulate a packet header (110) of a data packet (102) that is communicated by a wireless communications signal. The packet header (110) is modulated with a spread spectrum technique and the spread spectrum signal demodulator (210) produces a packet header detection signal (220) representing a successful detection of a predefined packet header value. A non-spread spectrum signal demodulator (212) is communicatively coupled to the spread spectrum signal demodulator (210) and demodulates, in response to the packet header detection signal (220), a non-spread spectrum modulated data payload within the data packet. A data output select (234) produces demodulated data produced by either one or both the spread spectrum signal demodulator (210) and the non-spread spectrum signal demodulator (212).
