AN-1496 Noise, TDMA Noise, and Suppression …
https://www.ti.com/lit/an/snaa033d/snaa033d.pdf
• TDMA Noise (“buzz”) in GSM mobile phones is generated from a 217Hz waveform which produces an audible noise when coupled into the audio path and conducts to the speaker, earpiece, or microphone4. Further details of this type of noise will follow. Before delving into solutions that minimize the problem TDMA Noise customers have ...
What is TDMA and How Does It Work?-HQT Solutions
http://www.hqtsolutions.com/news-information/tdma-how-it-works.html
And unlike 6.25 kHz transmission methods built on FDMA technology, TDMA fits seamlessly into existing licensed channel structures in UHF and VHF — known performance, no need for rebanding or relicensing, and no risk of new forms of radio channel interference. The choice of TDMA digital technology makes it quick and easy to gain spectrum ...

How to Suppress TDMA Noise. Inserting noise suppression filters in the microphone lines will prevent TDMA noise; however, the properties of these devices must not have a negative impact on the signals or audio quality. MEMS Microphone. With voice-activated applications, such as a smart speaker, voice becomes the interface for connecting to the ...
FDMA and TDMA Narrowband Digital Systems
http://info4u.us/FDMA-TDMA-Comparisons.pdf
Audio Quality: Much has been said about the improvements in audio quality of digital LMR radios compared to analog FM. Currently, both the FDMA and TDMA systems are utilizing the same vocoder, so apart from any differences in the speaker design or output; both systems' audio quality would be of a similar level.

For the wideband TDMA, multiple access spectral efficiency is given as: (6.4) η a = τ M t T f. where: τ = duration of a time slot that carries data. Tf = frame duration. Mt = number of time slots per frame. In Equation 6.4 it is assumed that the total available bandwidth is shared by all users. For the narrowband TDMA schemes, the total band ...
