摘要： Methods and apparatus are provided for spread spectrum communication having spectrum awareness and interference mitigation based on parameterizing an input signal having multiple mixed baseband signals. The method includes non-linearly transforming the input signal, removing carrier effects, removing higher order terms by passing the input signal through a low pass filter to produce a linear combination of data symbols and DC components, solving for the DC components, separating a plurality of mixed baseband signals from the input signal, and coordinate transforming each of the separated signals from polar coordinates to a Cartesian coordinates. A receiver is provided having: a non-linear transform operator receiving a digitized input signal and adapted to produce a linear combination of data symbols, DC components, and carrier effects; a low-pass filter connected to the non-linear transform for removing higher order terms; a separator unit for separating the plurality of mixed baseband signals; and, a coordinate transform for converting the separated signals from polar coordinates to Cartesian coordinates.

摘要： Methods and apparatus are provided for distributed polyphase spread spectrum communication and non-contiguous spectrum underlay. The method includes polyphase channelizing a direct sequence spread spectrum (DSSS) signal, determining available spectrum in an observed frequency range having a noise floor based on detection of polyphase users below the noise floor, distributing the polyphase channelized signal among the available spectrum, and interference mitigation using a combination of standard signal detection and cyclostationary feature detection methods. The apparatus includes: a first processor adapted to polyphase channelize a code division multiple access (CDMA) spectrum and a digitized RF bandwidth containing a discontiguous polyphase waveform distribution; a second processor adapted to detect occupied bands, interferers and polyphase users in a spectrum and determine discontiguous frequency opportunities based on the detected interferers and polyphase users; and a third processor adapted to allocate the polyphase channelized CDMA spectrum among available spectrum based on the discontiguous frequency opportunities.

摘要： A communications system (100) includes a multi-rate source coder (MRSC) (102), a variable size/rate buffer (VSRB) (112), a speech buffer (104), and a buffer control block (106). The variable size/rate buffer (112) includes a source coder bit buffer (SCBB) (114) and an adaptive transmit frame buffer (116). The source coder bit buffer (114) receives speech frames coded at different rates from the multi-rate source coder (102), and deposits an integer or non-integer number of frames in the adaptive transmit frame buffer (ATFB) (116). A receiver includes a seamless rate transition module (SRTM) (308) and an variable buffer (310). The seamless rate transition module (308) correlates speech data previously coded at different rates, and it then truncates or alternatively appends, concatenates, and warps the speech data to remove any annoying artifacts at the rate change boundary.
