        Description:
frequency timing estimator class does frequency/timing acquisition from scratch.It uses a bank of parallel correlators at each specified frequency. It then takes the max abs value of all these and passes it through a peak detector to find timing.


        Args:
	     seq1: sequence1 of kronecker filter, which is the given training sequence. 
	     seq2: sequence2 of kronecker filter, which is the pulse for each training symbol.
             factor: the rise and fall factors in peak detector, which is the factor determining when a peak has started and ended.  In the peak detector, an average of the signal is calculated. When the value of the signal goes over factor*average, we start looking for a peak. When the value of the signal goes below factor*average, we stop looking for a peak.
             alpha: the smoothing factor of a moving average filter used in the peak detector taking values in (0,1).
             freqs: the vector of normalized center frequencies for each matched filter. Note that for a training sequence of length Nt, each matched filter can recover a sequence with normalized frequency offset ~ 1/(2Nt).

        Description:
frequency timing estimator class does frequency/timing acquisition from scratch.It uses a bank of parallel correlators at each specified frequency. It then takes the max abs value of all these and passes it through a peak detector to find timing.


        Args:
	     seq1: sequence1 of kronecker filter, which is the given training sequence. 
	     seq2: sequence2 of kronecker filter, which is the pulse for each training symbol.
             factor: the rise and fall factors in peak detector, which is the factor determining when a peak has started and ended.  In the peak detector, an average of the signal is calculated. When the value of the signal goes over factor*average, we start looking for a peak. When the value of the signal goes below factor*average, we stop looking for a peak.
             alpha: the smoothing factor of a moving average filter used in the peak detector taking values in (0,1).
             freqs: the vector of normalized center frequencies for each matched filter. Note that for a training sequence of length Nt, each matched filter can recover a sequence with normalized frequency offset ~ 1/(2Nt).

	Description:
        This block is designed to perform frequency and timing acquisition for a known training sequence in the presense of frequency and timing offset and noise. Its input is a complex stream.  It has three outputs: 
 1)  a stream of flags (bytes) indicating the begining of the training sequence (to be used from subsequent blocks to "chop" the incoming stream,
 2)  a stream with the current acquired frequency offset, and
 3)  a stream with the current acquired peak of the matched filter 

	Internally, it consists of a user defined number of parallel matched filters (as many as the size of the freqs vector), each consistng of a frequency Xlating FIR filter with sample rate samp_rate, filter taps matched to the training sequence ts, and center frequency freqs[i]. The filter outputs are magnitude squared and passed through a max block and then through a peak detector. 
 
	Args:
	     ts: the training sequence. For example, in DSSS system, it's the chip-based spread training sequence. 
	     factor: the rise and fall factors in peak detector, which is the factor determining when a peak has started and ended.  In the peak detector, an average of the signal is calculated. When the value of the signal goes over factor*average, we start looking for a peak. When the value of the signal goes below factor*average, we stop looking for a peak. factor takes values in (0,1). 
	     alpha: the smoothing factor of a moving average filter used in the peak detector takeng values in (0,1).
	     samp_rate: the sample rate of the system, which is used in the freq_xlating_fir_filter.
	     freqs: the vector of center frequencies for each matched filter. Note that for a training sequence of length Nt, each matched filter can recover a sequence with normalized frequency offset ~ 1/(2Nt).

        Description:
frequency timing estimator class does frequency/timing acquisition from scratch.It uses a bank of parallel correlators at each specified frequency. It then takes the max abs value of all these and passes it through a peak detector to find timing.


        Args:
	     seq1: sequence1 of kronecker filter, which is the given training sequence. 
	     seq2: sequence2 of kronecker filter, which is the pulse for each training symbol.
             factor: the rise and fall factors in peak detector, which is the factor determining when a peak has started and ended.  In the peak detector, an average of the signal is calculated. When the value of the signal goes over factor*average, we start looking for a peak. When the value of the signal goes below factor*average, we stop looking for a peak.
             alpha: the smoothing factor of a moving average filter used in the peak detector taking values in (0,1).
             freqs: the vector of normalized center frequencies for each matched filter. Note that for a training sequence of length Nt, each matched filter can recover a sequence with normalized frequency offset ~ 1/(2Nt).
