When reset? is set to TRUE, the number of trailing symbols that are carried over to the next iteration during demodulation is upper bounded by [L + 4(13 + K)]/K , where L is the matched filter length in taps and K is the number of samples per symbol. For typical values of L = 25 (4 samples per symbol, filter length of 6 symbols) and K = 4, this value equals 23.25 symbols. Therefore when reset? is set to TRUE, a total of 1,024 PSK symbols must be passed to the demodulator to obtain at least 1,000 symbols at the output. This formula does not account for truncation due to any specified synchronization parameters.
