    1.2.2.3 Adaptive Equalizer - EQ The Adaptive Equalizer option in the Quasonix receiver improves reception in multipath channels by using digital signal processing to compensate for the signal distortion due to multipath. This option is compatible with standard telemetry applications and installations and it works with any brand of transmitter.

    The CRC™ also provides a 70 MHz IF output for each channel for troubleshooting purposes. These IF outputs are capped with 50 ohm terminators, and these should be left in place unless another 50 ohm load (such as a spectrum analyzer) is connected instead. Quasonix, Inc.

Bit Error Probability (BEP) is the calculated likelihood that a bit is in error. A very low BEP can be determined from only a few bits. BEP does not require any known data and can be determined quickly and accurately from demodulator statistics.

    Figure 52: Advanced Settings Window, Best Channel Selector Checked The Best-Channel Selector (BCS) is a revolutionary new feature, unique to the Quasonix RDMS™. Its purpose is to ensure that the back-panel data output from the Combiner is always optimal, even in rare cases where the Pre- Detection Diversity Combiner struggles relative to Channel 1 and Channel 2.

    LDPC encoding is intended to improve performance specifically under harsh conditions, which might have a negative effect on AFC tracking. In general, Quasonix recommends setting the AFC Mode to Off if possible. This recommendation is especially important for the best LDPC performance. Refer to section 5.4.3.5 for more information about AFC Mode.

  • Page 67: Figure 66: I And Q Data Streams Independently Encoded

    In this method, only one convolutional encoder is used for both the I and Q data. Figure 67: I and Q Data from Single Convolutional Encoder The appropriate decoder for this method is selected by setting Convolutional Symbol to Enabled (checked), as shown in Figure 68. Quasonix, Inc.

    Therefore, in AQPSK and AUQPSK modes, only the ‘A’ data will be decoded when Reed-Solomon decoding is enabled; ‘B’ data will be output without decoding. Reed-Solomon decoding and Viterbi decoding can be used together or separately. The Reed-Solomon decoder is selected by setting R-S Decoder to Enabled (checked), as shown in Figure 69. Quasonix, Inc.
