  • System and method for variable gain coder-decoder
    Patent number: 6507297
    Abstract: A variable gain coder-decoder is provided. The variable gain coder-decoder includes a variable gain amplifier in which the amplification gain may be adjusted in one-decibel steps. An analog to digital converter is connected to the variable gain amplifier. The analog to digital converter receives the amplified output of the amplifier, and performs an analog to digital conversion of the amplified output.
    Type: Grant

  • Dynamic range reduction circuitry for a digital communications receiver
    Patent number: 6445732
    Abstract: A method and apparatus which reduces the computational complexity of a receiver subject to power swings in excess of the power swings inherent in wireless communication from normal fading. To accomplish this, attenuation or some other form of signal modification occurs prior to the digital circuitry to reduce the required resolution of the analog to digital converter and other receiver components. A power signal estimator in conjunction with an attenuation control module may control the level of attenuation.
