These are the properties of class OfdmReceiverNoEstimation . 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: This class implements a receiver without any channel estimation. Note that this class also has the Properties of its base classes. The direct base class is simthlib::OfdmReceiver ; direct link to its propertylist should be propertylist_OfdmReceiver(). 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. output_length <sequencelength>, default "" -- The output length. 1 properties in this class. The above properties have been inherited from the base class simthlib::Receiver . diff_scheme <enum>, default "frequency" -- This parameter chooses the scheme how to fill the OFDM symbols in frequency and/or time direction. (WATCH OUT: The name is misleading. This property should rather be called 'fill_up_scheme'.) This is commonly used in different differential decoding schemes, e.g. differential decoding in frequency direction or differential decoding in time direction. WATCH OUT: The default here used to be frequency_snake, but since this contradicts common assumptions about the behaviour of OFDM receivers/transmitters, it was changed to the more textbook-like setting 'frequency'. This setting only has effect if the input_length is longer than num_carriers. oversampling <unsigned>, default "1" -- The oversampling rate used by the IDFT (IFFT) num_carrier <unsigned>, default "" -- The number of carriers guard_time <double>, default "0.0" -- The time duration of the guard interval in seconds. carrier_dist <double>, default "" -- The subcarrier distance (spacing) in Hertz. linear_phase_correction <bool>, default "false" -- Switchs linear phase correction 'off' and 'on', respectively. This could be useful if the received signal was sent over a channel with time delay (e.g. a WssusChannel). The receiver does not consider this time delay, therefore, the symbols sustain a multiplication with a complex factor in the frequency domain. This complex factor depends linearly on the frequency, i.e. the number of the subcarrier. This function computes this factor using the complex symbols filled into ofdmVector. num_phases <int>, default "0" -- Only active when linear_phase_correction is switched on: The number of different phases of the constellation diagram used by the modulator and demodulator. 7 properties in this class. The above properties have been inherited from the base class simthlib::OfdmReceiver . No properties defined in this particular class.
