function sym = vhtSIGAEncodeInterleaveMap(bits,phRot) %vhtSIGAEncodeInterleaveMap Encode, interleave and map VHT SIG-A bits % % Note: This is an internal undocumented function and its API and/or % functionality may change in subsequent releases. % % SYM = vhtSIGAEncodeInterleaveMap(BITS,PHROT) performs BCC encoding, % interleaving and constellation mapping according to Sections 18.3.5.6, % 18.3.5.7 and 18.3.5.8. % % SYM is a Nsd-by-Nsym matrix of complex numbers representing the % encoded, interleaved and mapped bits. % % BITS is a column vector of bits to encode. % % PHROT is a scalar or row vector with Nsym elements of the phase % rotation to apply to each symbol during constellation mapping. If only % one phase rotation is provided all symbols are rotated by the same % amount. % Copyright 2016 The MathWorks, Inc. %#codegen % Encode according to Section 18.3.5.6 encodedSIG = wlan.internal.wlanBCCEncode(bits,'1/2'); % Interleaving according to Section 18.3.5.7 numSym = 2; numBPSCS = 1; numCBPS = 48; interleaveFormat = 'NON_HT'; interleavedData = zeros(numCBPS,numSym); for i = 1:numSym interleavedData(:,i) = wlan.internal.wlanBCCInterleave( ... encodedSIG((i-1)*numCBPS+(1:numCBPS).',:),interleaveFormat,numCBPS,numBPSCS); end % BSPK constellation mapping according to Section 18.3.5.8 with phase % rotation sym = wlan.internal.wlanConstellationMapper(interleavedData,numBPSCS,phRot); end
