Detailed Description

Offers some functions to convert a certain type of a sequence to another type.

E.g: a LlrSeq can be converted to a LlvSeq with llrSeq2llvSeq().

Function Documentation

unsigned bits2value (  BitSeq::const_iterator  first, BitSeq::const_iterator  behindLast )

Converts a certain number of bits to its integer value, i.e. 101 to 5.

bool value2bit (  unsigned  index, size_t  bitPos )  [inline]

Returns the bit at the position bitPos from the bit representation of the given value.

void value2bits (  unsigned  index, BitSeq::iterator  first, BitSeq::iterator  behindLast )

Returns the x leftmost bits of the binary representation of the decimal value passed by index, where x=behindLast-first.

double llrValue2llvValue (  LlrType  llrValue, bool  bitValue )  [inline]

Converts an LLR to an LLV for the specified bit, i.e. the return value corresponds to the log propability that the given bitValue is 'correct' depending on the given LLR value. The following equation between LLR and LLV holds: LLR = LLV[0] - LLV[1], where LLV[0] is the LLV for the bit value 0 and LLV[1] is the LLV for the bit value 1.

bool llrValue2bit (  LlrType  llrValue  )  [inline]

Converts an LLR value to the 'hard' estimated bit decision. A negative LLR value belongs to the bit 1, a positve LLR value belongs to 0.

LlvType bit2llvValue (  bool  bit, bool  index )  [inline]

Converts a bit value to the (bit)LLV value. If bit==index, 1.0 is returned, else -1.0.

LlrType bit2llrValue (  bool  bit  )  [inline]

Converts a bit to an LLR. The bit 1 is converted to -2.0, the bit 0 is converted to 2.0. Thus LLV[0]-LLV[1] = LLR as described in the documentation of llrValue2llvValue() holds.

void bitSeq2llvSeq (  const BitSeq &  bits, LlvSeq &  llv )

Convert a BitSeq into a LlvSeq.

void bitSeq2llvSeq (  const BitSeq &  bits, LlvSeq *  llv )

Convert a BitSeq into a LlvSeq.

void llrSeq2bitLlvSeq (  const LlrSeq &  llr, LlvSeq &  llv )

void llrSeq2bitLlvSeq (  const LlrSeq &  llr, LlvSeq *  llv )

void llrSeq2bitSeq (  const LlrSeq &  from, BitSeq &  bits )

void llrSeq2bitSeq (  const LlrSeq &  from, BitSeq *  bits )

void llvSeq2bitLlvSeq (  const LlvSeq &  from, LlvSeq &  bitLlv )

void llvSeq2bitLlvSeq (  const LlvSeq &  from, LlvSeq *  bitLlv )

void llvSeq2llrSeq (  const LlvSeq &  from, LlrSeq &  to, size_t  outputLength = 0 )

void llvSeq2llrSeq (  const LlvSeq &  from, LlrSeq *  to, size_t  outputLength = 0 )

void bitLlvSeq2llvSeq (  const LlvSeq &  from, LlvSeq &  to, unsigned  bitsPerState = 0 )

void bitLlvSeq2llvSeq (  const LlvSeq &  from, LlvSeq *  to, unsigned  bitsPerState = 0 )

void bitSeq2IntSeq (  const simth::BitSeq &  bs, simth::checkedVector< int > &  IntSeq, int  numBits )

Convert a BitSeq into an integer sequence Parameters: bs  Input sequence IntSeq  Output sequence numBits  The number of bits converted into an interger value

size_t getSymSeqLength (  size_t  bitSeqLen, unsigned  bitsPerSym, ConversionFlag  flag = FIT )
