A method for selecting the language for a character sequence fed into a data processing device, wherein decision trees are trained for different characters on the basis of lexicons of predetermined languages. The decision trees describe language probabilities on the basis of characters in the environments of the characters. The decision trees for at least some of the characters of the character sequence fed into the data processing device are traversed, thus obtaining a probability of at least one language for each character. The language for the character sequence is selected on the basis of the probabilities obtained.

A signature sequence employed in a wireless transmission over a channel is detected and utilized. The signature sequence is selected from a set of sequences formed by delay-Doppler shifts of a base sequence. Preferably but not exclusively, the set of sequences is formed by circular delay-Doppler shifts of the base sequence. The base sequence can be, for example, an m-sequence. A received signal is obtained from a received wireless transmission. A candidate sequence selector (90) selects a candidate sequence from among a set of sequences for evaluation as the signature sequence, the set of sequences having been formed by sequence set generator (88) as delay-Doppler shifts of a base sequence. An image former (82) uses the base sequence and the received signal to form a delay-Doppler image with respect to an image area pertinent to the candidate sequence. A metric analyzer (84) computes a metric over the image area pertinent to the candidate sequence and uses the metric to determine if the signature sequence is the candidate sequence. A sequence utilization device (76) can use the signature sequence to identify another transceiver unit which sent the wireless transmission, and / or use the signature sequence for synchronization with another transceiver unit which sent the wireless transmission.

Orthogonal frequency division multiplexing (OFDM) is a spectrally efficient multicarrier modulation technique for high speed data transmission over multipath fading channels, but has low power efficiency. OFDM signals have large crest factors, or peak-to-average power ratios (PARs) which lead to power inefficiency in the RF portion of the transmitter. Selected mapping can be used to reduce the PAR of an OFDM signal and is distortionless. A technique is disclosed that links the index of a phase rotation sequence used in selected mapping to the location of pilot tones that are used to estimate the channel. Each pilot tone location—phase sequence selection produces a different PAR value for the time-domain OFDM signal, and the signal with the lowest PAR value is transmitted. The technique is “blind” in that the optimum pilot tone location—phase sequence index is not transmitted as side information. A technique to blindly detect the optimum index at the receiver is also disclosed.
