Talk:Guided Tutorial PSK Demodulation

I greatly appreciate this guided tutorial. I had some difficulties following along, so the following might help others using this tutorial.
 * Implementation Hints

* Hints for mpsk_rrc_rolloff.grc 1. Constellation Modulator property Constellation = qpsk_const This setting uses the Constellation Rect. Object id qpsk_const (aka <con...(m=4))

* Hints for mpsk_stage1.grc 1. Constellation Modulator property Constellation = qpsk_const This setting uses the Constellation Rect. Object id qpsk_const (aka <con...(m=4)) 2. Variable id rrc_taps value is firdes.root_raised_cosine(1.0,samp_rate,samp_rate/sps,excess_bw,11*sps). See /*!     * \brief design a Root Cosine FIR Filter (do we need a window?) *     * \param gain            overall gain of filter (typically 1.0) * \param sampling_freq  sampling freq (Hz) * \param symbol_rate    symbol rate, must be a factor of sample rate * \param alpha          excess bandwidth factor * \param ntaps          number of taps */
