BER and bit and symbol stream calculation methods.

Functions

`adjust_data_length`(data_tx, data_rx[, ...])	Adjust the length of data_tx to match data_rx, either by truncation or repeating the data.
`cal_ber_nosyncd`(data_rx, data_tx)	Calculate the BER between a received bit stream and a known bit sequence which is not synchronised.
`cal_ber_syncd`(data_rx, data_tx[, threshold])	Calculate the bit-error rate (BER) between two synchronised binary data signals in linear units.
`fftconvolve`(in1, in2[, mode, axes])	Convolve two N-dimensional arrays using FFT.
`find_sequence_offset`(x, y[, show_cc])	Find the time shift between two input signals that might contain errors might contain errors, using cross-correlation between data_rx and data_tx.
`find_sequence_offset_complex`(x, y)	Find the offset of one sequence in the other even if both sequences are complex.
`sync_and_adjust`(data_tx, data_rx[, adjust])	Synchronize and adjust length of received and transmitted data sequence.
`sync_rx2tx`(data_tx, data_rx, Lsync[, imax])	Sync the received data sequence to the transmitted data, which might contain errors.
`sync_tx2rx`(data_tx, data_rx, Lsync[, imax])	Sync the transmitted data sequence to the received data, which might contain errors.
