wlanRecoveryConfig Properties

Define parameter values for data recovery

The wlanRecoveryConfig object specifies properties for recovering data from IEEE® 802.11 transmissions.

After you create an object, use dot notation to change or access the object parameters. For example:

Create a wlanRecoveryConfig object. Then modify the default setting for the OFDMSymbolOffset property.

cfgRec = wlanRecoveryConfig;
cfgRec.OFDMSymbolOffset = 0.65;

Date Recovery Configuration

OFDM symbol sampling offset represented as a fraction of the cyclic prefix (CP) length, specified as a scalar value from 0 to 1. This value indicates the start location for OFDM demodulation, relative to the beginning of the cyclic prefix. OFDMSymbolOffset = 0 represents the start of the cyclic prefix and OFDMSymbolOffset = 1 represents the end of the cyclic prefix.

Data Types: double

Equalization method, specified as 'MMSE' or 'ZF'.

  • 'MMSE' indicates that the receiver uses a minimum mean square error equalizer.

  • 'ZF' indicates that the receiver uses a zero-forcing equalizer.

Example: 'ZF'

Data Types: char | string

Pilot phase tracking, specified as 'PreEQ' or 'None'.

  • 'PreEQ' — Enables pilot phase tracking, which is performed before any equalization operation.

  • 'None' — Pilot phase tracking does not occur.

Data Types: char | string

Maximum number of decoding iterations in LDPC, specified as a positive scalar integer. This parameter is applicable when channel coding is set to LDPC for the user of interest.

For information on channel coding options, see the 802.11™ format configuration object of interest.

Data Types: double

Enable early termination of LDPC decoding, specified as a logical. This parameter is applicable when channel coding is set to LDPC for the user of interest.

  • When set to false, LDPC decoding completes the number of iterations specified by MaximumLDPCIterationCount, regardless of parity check status.

  • When set to true, LDPC decoding terminates when all parity-checks are satisfied.

For information on channel coding options, see the 802.11 format configuration object of interest.
