System and method for optimized receiver performance in a low intermediate frequency architecture for edge

A method for use in a near zero intermediate frequency wireless architecture comprising:

• receiving an analog signal;
• mixing the received analog signal with a local oscillator signal to create a mixed signal having a low intermediate frequency between approximately 125 kHz and 145 kHz;
• filtering the mixed signal to minimize a direct current (DC) component introduced into the mixed signal by the local oscillator signal;
• converting the mixed signal from an analog signal to a digital signal;
• rejecting an interferer image portion of the mixed signal;
• minimizing DC introduced into the mixed signal;
• downconverting the mixed signal;
• and
• minimizing DC remaining at the intermediate frequency after the signal is downconverted.

A method for a near zero intermediate frequency wireless device comprising:

• mixing a received analog signal with a local oscillator signal to create a mixed signal having an intermediate frequency between 101 kHz and 199 kHz;
• compensating the mixed signal to minimize a direct current (DC) component introduced into the mixed signal by the local oscillator signal;
• rejecting an interferer image portion of the mixed signal;
• minimizing DC introduced into the mixed signal before final downconverting of the mixed signal;
• and
• minimizing DC remaining at the intermediate frequency after downconverting the mixed signal.
