Description |
|---|---|
CS |
Channel Sounding |
PDE |
Phase-based Distance Estimation |
RTP |
Round-Trip Phase |
RTT |
Rount-Trip Time |
ToF |
Time of Flight |
MD |
Measuring Device |
RD |
Reflector Device |
EDLC |
Early Detect Late Commit |
SFD |
Start-of-Frame Delimiter |
T_FCS |
The RF circuitry locks to the measurement channel (f_i). Devices can also use this time for additional internal calibrations, if necessary. The initiator may start to ramp up its output signal toward the end of this step. |
T_FM |
Time for Frequency Measurement |
T_SY |
Time for Synchronization sequence (CS packet) |
T_IP1 |
Interlude Period 1 - transition from TX to RX and the other way around when transmitting in mode 1 (Tn-Tn) |
T_IP2 |
Interlude Period 2 - transition from TX to RX and the other way around when transmitting in mode 2 (Tn-Tn) |
T_GD |
Transition time between packet and tone |
T_RD |
Ramp-Down time for transmission |
T_PM |
Single-antenna Phase Measurement period |
N_AP |
Number of Antenna Paths |
T_SW |
Antenna-Switching period |
AGC |
Automatic Gain Control |
ADC |
Analog-to-Digital Conversion |
CDE |
Complex Distance Estimation |
IFFT |
Inverse Fast Fourier Transform |
