Recover bits from VHT-Data field

recovers `dataBits`

= wlanVHTDataRecover(`rxDataSig`

,`chEst`

,`noiseVarEst`

,`cfgVHT`

)`dataBits`

, a column vector of bits, from
`rxDataSig`

, the received VHT-Data field of a
very-high-throughput (VHT) single-user transmission. The function recovers
`dataBits`

by using `chEst`

, a channel
estimate for the occupied subcarriers, `noiseVarEst`

, an
estimate of noise variance, and `cfgVHT`

, a configuration
object that contains VHT transmission parameters.

For more information about the VHT-Data field, see VHT-Data Field.

specifies algorithm options by using one or more name-value pair arguments, in
addition to any input argument combination from previous syntaxes. For example,
`dataBits`

= wlanVHTDataRecover(___,`Name,Value`

)`'LDPCDecodingMethod','layered-bp'`

specifies the layered
belief propagation low-density parity-check (LDPC) decoding algorithm.
