Effect of different interferer data rates on GPS acquisition

An effort to reach at an expression for the allowable TX noise levels into the GPS band for the WCDMA transmitters coexisting with the GPS service in a smartphone is made. These allowable noise levels will be for a certain tolerable amount of signal to noise ratio degradation. In developing these equations, the total system noise contributors are taken into consideration with practicality. These contributors include thermal, jammer, noise figure and local oscillator spurious emissions. The effect of changing data rates in WCDMA transmission on GPS acquisition will be the study in this paper.
