propertylist_AdaptiveModulatorBase ( not_a_function ) [related]

These are the properties of class AdaptiveModulatorBase . 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: A block that performs subcarrier-wise adaptive modulation. Several loading algorithms are available, as chosen by the loading_scheme property. The information about the channel transfer function can either be obtained by the second input interface, or, if it is unconnected, this block will internally look for the channel block and directly obtain the channel transfer function from there.
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.

avg_bits_per_symbol

<unsigned>, default "" -- Average bits per symbol, i.e. the bitrate.

num_carrier

<unsigned>, default "" -- Number of subcarriers over which the adaptive modulation is computed.

loading_algorithm

<enum>, default "ccb" -- The loading algorithm to be used.

power_scaling

<bool>, default "true" -- Whether the powers should also be scaled or not.

modulation_schemes

<list_string>, default "NONE BPSK QPSK 8-RAM 16-QAM 32-RAM 64-QAM" -- A space-separated list of all modulation schemes that should be used. Watch out: You need to specify constellations that are large enough so that the average number of bits can still be transmitted. Possible values are UNMODULATED or NONE, BPSK or 2-PSK, QPSK or 4-PSK, 8-PSK, 8-RAM, 4-QAM, 16-QAM, 32-QAM, 32-RAM, 64-QAM, 128-QAM, 128-RAM, 256-QAM

mapping

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

scale_re

<vector_double>, default "" -- Space-separated list of scaling values for the different available modulation schemes. Usually unused (i.e. no extra scaling).

scale_im

<vector_double>, default "" -- Space-separated list of scaling values for the different available modulation schemes. Usually unused (i.e. no extra scaling).

split_ccb_num_groups

<unsigned>, default "1" -- Only for split_ccb loading scheme

carrier_dist

<double>, default "0.0" -- Only necessary when the channel transfer function is obtained internally directly from the channel: The carrier distance of the transmitter.

oversampling

<unsigned>, default "0" -- Only necessary when the channel transfer function is obtained internally directly from the channel: The oversampling of the transmitter.

guardtime

<double>, default "0.0" -- Only necessary when the channel transfer function is obtained internally directly from the channel: The guard time of the transmitter.

symbol_interleaving_length

<unsigned>, default "1" --

symbol_interleaving_rows

<unsigned>, default "1" --

symbol_interleaving_cols

<unsigned>, default "1" --

symbol_interleaving_planes

<unsigned>, default "1" --
