Se-Kab Oh, Jae-Myeong Choi, Heau-Jo Kang · The Journal of Advanced Navigation Technology · 2009
In this paper, we study the method of noise analysis for analysing TDMA noise in a GSM mobile phone and describe the cause of TDMA noise. And we reduced noise by 9dB, 3.5dB, 6dB, using MIC shielding, equipped bead or capacitance, connected PCB ground based on the difference analysis method, which is one of common noise analysis methods.
