5G Candidate - UFMC

1. Modulation Scheme

Modulation Scheme

Choices: FBMC-OQAM | UFMC | GFDM | F-OFDM

Default: FBMC-OQAM

Select the modulation scheme for 5G.

2. UFMC Settings

FFT Length

Range: 4 to 16384

Default: 64

Set the FFT length of the OFDM signal. This value will be clipped to the nearest power of 2.

Guard Lower Subcarriers

Range: 0 to FFT Length / 2

Default: 6

Set the number of lower guard subcarriers. No data will be transmitted on these subcarriers.

Guard Upper Subcarriers

Range: 0 to FFT Length / 2

Default: 5

Set the number of upper guard subcarriers. No data will be transmitted on these subcarriers.

Number of Multicarrier Symbols

Range: 1 to 2000

Default: 64

Set the number of OFDM symbols in a frame that usually includes preamble symbols and data symbols.

Idle Interval

Range: 0 to 200 ms

Default: 4 us

Set the idle interval in-between OFDM frames in seconds. When idle interval is set to zero, a continuous waveform will be generated.

System Sample Frequency

Range: 1 kHz to 4 GHz

Default: 20 MHz

Set the system sampling rate in Hz.

3. Subband Configuration

Subband Subcarrier Start

Set the subcarrier start index of subband configuration, the subband subcarrier end is coupled after it changes.

Subband Subcarrier End

Set the subcarrier end index of subband configuration, the subband subcarrier start is coupled after it changes.

Subband Size

Set the number of subcarriers for each subband, the subband end is coupled after it changes.

Number of Subbands

Set the number of subbands, the subband end is coupled after it changes.

Skip DC

Choices: Yes | No

Default: Yes

Set if DC is skipped between subbands. It is editable when DC is on the edge of subband, otherwise it is set to No and read-only.

Subband Filter

Bring up the UFMC Subband Filter Editor to set the filter type and parameters.
