Member Function Documentation

virtual void simthlib::AdaptiveDemodulatorBase::demodulate ( const simth::ModSeq & receivedSym,

simth::LlvSeq * correspondingLlvValues,

double noise = 0,

const simth::ModSeq * trans = NULL,

simth::LoadingInfoSeq * loading = NULL

) [protected, virtual]

Demodulates a sequence of received data words to a sequence of log-likelihood-values (Llv).

virtual void simthlib::AdaptiveDemodulatorBase::demodulate ( const simth::ModSeq & receivedSym,

simth::LlrSeq * correspondingLlrValues,

double noise = 0,

const simth::ModSeq * trans = NULL,

simth::LoadingInfoSeq * loading = NULL

) [protected, virtual]

Demodulates a sequence of received data words to a sequence of log-likelihood-ratio (llr) values; each LLR-value represents the hard decisions of one bit and the probability of this decision. The hard decision (the bit itselfs) is determined by the sign of the LLR-Value, whereas the probability is described by the absolute value of the log-likelihood ratio:

/f$llr = ln(p(1)/p(0))/f$

propertylist_AdaptiveDemodulatorBase ( not_a_function ) [related]

These are the properties of class AdaptiveDemodulatorBase . This list is auto-generated from the XML-Devicelist of this device by means of an XSLT transformation script.
Description of this device in the XML file: Adaptive demodulation.
Note that this class also has the Properties of its base classes. The direct base class is simth::Device ; direct link to its propertylist should be propertylist_Device(). The list below usually includes the properties that have been inherited from the base classes; the properties which belong only to this class can be found at the end of this list.

input_length

<sequencelength>, default "" -- The input length. Needs to be the same as the Modulator's output length. (FIXME: Why does it have to be fixed here?)

mapping

<enum>, default "gray" -- bit mapping scheme

avg_bits_per_symbol

<unsigned>, default "" -- The average number of bits per modulation symbol.

csi_only_for_reliabilities

<bool>, default "false" -- If true, then the Channel State Information (CSI) at the second input interface is only used for calculating the reliabilities of the output. If false (default), then the CSI is used for both equalising the received signal and calculating the reliabilities of the output. If the second input interface is not connected, then this property has no effect.

output_type

<enum>, default "LLR" -- The type of the output interface

symbol_interleaving_length

<unsigned>, default "1" --

symbol_interleaving_rows

<unsigned>, default "1" --

symbol_interleaving_cols

<unsigned>, default "1" --

symbol_interleaving_planes

<unsigned>, default "1" --
