Prefixes
| Symbol | Prefix | Value |
|---|---|---|
| n | nano | 10 -9 |
| µ | micro | 10 -6 |
| k | kilo | 10 3 |
| M | mega | 10 6 |
B |
|
| BCC | binary convolutional code |
| burst | A continuous signal with idle interval or quiet time at both ends. In the toolkit, one frame of the signal is called one burst. |
C |
|
| CCK | complementary code keying |
| channel | The waveform after MIMO combining (spatial multiplexing) of spatial streams. |
| chip EVM | Each spreading bit is called a chip. The symbols are spread by a chip sequence. The error between the ideal signal and the received signal in each chip period is averaged over the signal to give the chip EVM. |
| CRC | cyclic redundancy check |
| CW | continuous wave |
| CPE | common pilot error |
D |
|
| DAC | digital-to-analog converter |
| DBPSK | differential binary phase-shift keying |
| DQPSK | differential quadrature phase-shift keying |
| DSSS-OFDM | direct sequence spread spectrum-orthogonal frequency division multiplexing |
| DSSS | direct sequence spread spectrum |
| DUT | device under test |
E |
|
| ENBW | equivalent noise bandwidth |
| ERP | extended rate physical layer |
| ERP-OFDM | extended rate physical layer-orthogonal frequency division multiplexing |
| ERP-PBCC | extended rate physical layer-packet binary convolutional coding |
| EVM | error vector magnitude |
F |
|
| FCS | frame check sequence |
| FFT | fast Fourier transform |
| FEC | forward error correction |
G |
|
| Gated spectrum | A spectrum of the signal acquired in the time interval when the signal is active. This acquisition can be triggered by the transition of the signal from an inactive state to an active state. The gate is preferred to be the interval when the signal is active. |
H |
|
| header checksum | Performs CRC16 check on the received header. |
| HT | high-throughput |
| HT-SIG | high-throughput SIGNAL |
I |
|
| I | in-phase |
| I/Q | The translation of the magnitude and phase data of a signal from a polar coordinate system to a complex Cartesian (X,Y) coordinate system. |

| LTF | long training field |
| LTS | long training symbol |

P |
|
| PAPR | peak-to-average power ratio |
| PBCC | packet binary convolutional coding |
| PLCP | physical layer convergence procedure |
| PPDU | procedure protocol data unit |
| PSD | power spectral density |
| PSK | phase-shift keying |
| PvT | power versus time |
Q |
|
| Q | quadrature-phase |
R |
|

V |
|
| VBW | video bandwidth |
