1. An apparatus comprising:
a microprocessor; and a wireless communication interface configured to perform at least one of receiving a first radio signal or transmitting a second radio signal, said wireless communication interface electrically coupled to at least one of an analog-to-digital converter (ADC) or a digital-to-analog converter (DAC); wherein said microprocessor is configured to execute at least one of a base-band encoder software program or a base-band decoder software program; wherein said base-band encoder software program is configured to produce a first encoded bit stream by performing at least one of the following functions: source encoding of a first bit stream, encryption, channel encoding, multiplexing, modulation, frequency spreading, and media access control; wherein said DAC is configured to output an analog signal corresponding to said first encoded bit stream; wherein said ADC is configured to output a second encoded bit stream corresponding to an analog signal produced by said wireless communication interface; and wherein said base-band decoder software program is configured to produce a second bit stream corresponding to said second encoded bit stream by performing at least one of the following functions: media access control, frequency de-spreading, de-modulation, de-multiplexing, channel decoding, decryption, or source decoding. |
