Channel characteristics from the literature.
| Gain | Phase | Linearity of channel | Noise in channel | Gain |
| Capacitive coupling HBC |
| Static body behavior | Bandpass profile [31] | Non | Non | Non | Influence by electrode [35] | Better results in limbs [54] | TX GND electrode strengthen signal [19] |
| Dynamic body behavior | Movement sensitive [54, 55] | Non | Non | Non | Joint flexion cause gain variate in 2 dB [96] |
| Galvanic coupling HBC |
| Static body behavior | Higher gain in trunk and back [54] High-pass profile [45] High-pass profile [59] | Decrease [45] | Linear channel [59] | AWGN [41, 59, 92] |
| Dynamic body behavior | Not sensitive in sitting & waling [54] Increase as joint flexion [56] Joints and biceps muscle have a great effect [57] | Decrease trend [57] Not sensitive by movement [57] | Non | AWGN [57] |
