[. . . ] Four coding levels (called RS Efficiency) are specified, which allow for more or less error correction within a block. The percentages in the following list of coding levels, relate the number of information symbols (user data) to the block length, a block comprises user data and parity check symbols: ROBUST: 60% NORMAL: 75% FAST: 90% OFF: 100% (i. e. , no error correction) The level of RS Efficiency is automatically detected by the demodulator. After successful synchronization, it may take several tens of seconds before any text is output in the GUI. 114 Transmission Modes Manual V6. 6. 5. 0 WAVECOM Decoder CODAN Parameter Frequency range System Speed Modulation Receiver settings Input(s) Additional Info Value HF FSK, Digital Selcal 100. 0 Baud FSK DATA, CW, LSB or USB AF-IN, IF-IN-VAR, IF-IN-10. 7 or IF-IN-21. 4 ITU R M. 493 alphabet CODAN SELCAL operates with 100. 0 baud and can be started by selecting the mode. A preamble of at least 100 dot reversals which are 50 changes between "0" and "1" (low and high bit) precedes the data block. Digital MARK "1" is represented by a frequency of 1870 Hz and SPACE by 1700 Hz. The dot pattern is followed by a word synchronization sequence called the "phasing preamble". This sequence is followed by the data block with different control characters and the message. Selecting Options/Display offers the option of an ASCII or RAW bits display. CODAN-9001(Option) Parameter Frequency range System Center frequency Shift/Bandwidth Speed Modulation Receiver settings Input(s) Additional Info Value HF Half-duplex asynchronous adaptive ARQ In the range (-3100, 3100) [Hz]; automatic frequency control (AFC): +/-37. 5 Hz N/A 16 x 75 Baud Differential PSK4A; 16 tones DATA, CW, LSB or USB AF-IN, IF-IN-VAR, IF-IN-10. 7 or IF-IN-21. 4 Optional Mode ITA-5 CODAN-9001 is an asynchronous adaptive ARQ system. The modulation type is differential quaternary phaseshift keying (differential PSK4A). The demodulator output consists of a bit-stream that may have been derandomized if desired. In such a case, the required derandomization sequence is generated by a linear shift register (LSR) comprising 27 stages. The user can specify a 27-digit combination of 0s and 1s to be used for the initialization of the LSR. Alternatively, the initialization pattern can be determined automatically from the signal at hand. All options related to derandomization and initialization of the LSR can be set in the dialog "CODAN-9001 Options" (see below) which is accessed via "Options, CODAN-9001 Options. . . " Manual V6. 6. 5. 0 WAVECOM Decoder Transmission Modes 115 A bit-error rate (BER) measurement is performed, and the BER is displayed in the status line. Two different ways of BER measurement are available: BER is determined by considering only preamble- and sync-blocks BER is determined by considering preamble-, sync-, RQ-, and data-blocks After successful synchronization, it may take several tens of seconds before the bit-stream (in hexadecimal format) is output in the GUI. The output data can be displayed in one of two available formats: "BINARY" (0s and 1s) or "HEX" (hexadecimal numbers). The selection of the desired output format can be performed in the dialog "Display", which is accessed via "Options, Display. . . " XX screen shot The user can specify the polarity of the received signal, i. e. NOR(mal) or INV(erse). COQUELET-8 Parameter Frequency range System Speed Modulation Receiver settings Input(s) Additional Info Value HF MFSK, Simplex 37. 5, 50. 0 or 75. 0 ms MFSK DATA, CW, LSB or USB AF-IN, IF-IN-VAR, IF-IN-10. 7 or IF-IN-21. 4 ITA-2 COQUELET-8 is a MFSK (Multiple Frequency Shift Keying) system and like the PICCOLO system translates an ITA-2 character into a sequence of two tones. The first group of tones contains 8 tones (1 - 8) and the second group the tones 5 - 8. Coquelet-8 is a synchronous system with a tone duration of 75. 0 ms, 50. 0 ms or 37. 5 ms. One ITA-2 character is transmitted in 75 or 150 ms, which is equivalent to 50 or 100 Baud Baudot with 1. 5 stop bit (codeword length 7. 5 Bit). Transmissions start with a synchronization preamble, and end with several EOT characters.
