Syntax

y = wlanBCCEncode(bits,rate)

Description

example

y= wlanBCCEncode(bits,rate)convolutionally encodes the binary inputbitsusing a binary convolutional code (BCC) at the specifiedrate。bbc在IEEE定义®802.11™-2012 Sections 18.3.5.6 and 20.3.11.6.

Examples

collapse all

Open Live Script

Encode a sequence of data bits by using a BCC of rate 3/4.

Create the sequence of data bits.

dataBits = randi([0 1],300,1);

BCC-encode the data bits.

encodedData = wlanBCCEncode(dataBits,'3/4'); size(encodedData)
ans =1×2400 1
Open Live Script

Encode two streams of data bits by using a BCC of rate 1/2.

Create the sequence of data bits.

dataBits = randi([0 1],100,1,'int8');

Parse the sequence of bits as defined in IEEE® 802.11™-2012 Section 20.3.11.5 and IEEE® 802.11ac™-2013 Section 22.3.10.5.2.numESis the number of encoded streams.

numES = 2; parsedData = reshape(dataBits,numES,[]).';

BCC-encode the parsed sequence.

encodedData = wlanBCCEncode(parsedData,1/2); size(encodedData)
ans =1×2100 2

Input Arguments

collapse all

Input sequence with data bits to encode, specified as a binary matrix. The number of columns must equal the number of encoded streams. Each stream is encoded separately.

Data Types:double|int8

Code rate of the binary convolutional code (BCC), specified as a scalar, character array, or string scalar.ratemust be a numeric value equal to 1/2, 2/3, 3/4, or 5/6, or a character vector or string scalar equal to'1/2','2/3','3/4', or'5/6'。

Example:'1/2'

Data Types:double|char|string

Output Arguments

collapse all

Binary convolutionally encoded output, returned as a binary matrix of the same type ofbits。The number of rows ofyis the result of dividing the number of rows of inputbitsbyrate, rounded to the next integer. The number of columns ofyis equal to the number of columns ofbits。
