摘要： Reproduction of a data signal which is stored on a source media (140) or distributed via a communication network is controlled by inserting master tag data (130) and control tag data (160) into the data signal. A player/recorder (150) inserts an additional generation of control tag information each time a copy of the media is made. If the number of generations of the control tag information is above a threshold value, reproduction of the data signal may be inhibited. For example, if the data signal comprises audio data, the player/recorder may only allow playing of the audio signal over speakers but will not allow recording. The playing and recording of associated signals, which accompany an audio signal, may also be controlled. The master tag data (130) and control tag data (160) may be provided as spread spectrum signals which are spectrally shaped and power-adjusted according to the data signal to render them imperceptible in the data signal.

摘要： Non-coherently demodulated signals are efficiently decoded using a non-complex system that is independent of the fading statistics of the channel. A symbol metric calculator (406) receives a signal-to-noise ratio (404) and symbols from a non-coherently demodulated signal (402) to efficiently produce weighted symbol metrics (408). A symbol metric deinterleaver (410) is then used to deinterleave the weighted symbol metrics. A decoder (414) produces a decoded bit sequence (416) based on the deinterleaved weighted symbol metrics (412).

摘要： The method involves modulating a signal input to a transmitter or write unit for transmission to a receiver or reader unit. The transmitter generates angle modulated pulses with successive opposed angular modulations during a pulse period superimposed to form a folding pulse on which information is superimposed by modulation or encoding. The received folding pulses is filtered in two or more dispersion filters connected in parallel pairs with frequency dependent group transmission time characteristics matched to the angular modulation of the pulses. The filters output a pair of combined signals consisting of a time compressed signal with increased amplitude and an extended signal with reduced amplitude which are fed to a second superimposition element. -

摘要： The invention relates to a novel code division multiple access, code multiplex (CDMA) system structure which is identical to the structure of a CDMA system operating with direct code spread (DS, direct sequence) but which operates by a multiple carrier system (MC). The multiple carrier system is introduced by appropriate selection of the spread code with the result that signal generation in CDMA systems is unified with DS and with MC, and known joint detection processes with or without diversity reception are used.

摘要： A receiver unit (121) cancels interference in a composite received signal (102) by synthesizing a replica of the composite received signal which accounts for multipath effects (echoes) of the composite received signal. The receiver unit (121) is comprised of a RAKE receiver (122), which provides correlation peaks of the various multipath echoes. The correlation peaks are characterized by time delays and respective amplitudes and phases of the various multipath echoes. By generating a cancellation signal (124) which utilizes the correlation peaks of each multipath echo, a signal (130) more representative of the actual composite received signal is utilized to improve the degree of interference cancellation.

摘要： A selective call communication system (10) has a selective call device (100) for transmitting a frequency hopped spread spectrum signal (320) encoded as Reed Solomon code words and modulated as a four-level frequency shift keying (4FSK) signal. A base site transceiver (156) receives the signal on a plurality of narrow band channels. A digital signal processor (DSP) (152) performs a fast Fourier transform on the signal to generate frequency samples. The DSP (152) has a comparator (342) that compares a 4FSK symbol to a predetermined threshold, a determinator (344), in response to the comparator (342), determines when there is an interference signal jamming the narrow band channel, an erasure marker (346) marks a position in the Reed Solomon symbol determined to be jammed as an erasure and an error correcting code (348) corrects errors in the Reed Solomon code words marked with erasures.

摘要： A determinant expressing the relation between the sequence of symbol vectors b(k) transmitted from L communicators through code division multiplexing and the sequence of compressed-back output vectors y(k) of received signals taking the cross correlation of the spread-spectrum sequence of the sequence of the vectors b(k) into account is limited within the range of from k-g to k+g where k is the symbol timing and g is the symbol time. The compressed-back outputs of the received signals within the limited range are inputted to a shift register having 2g+1 stages. A partial correlation matrix calculating section (26) calculates partial correlation matrixes R (1), R (0), and R (-1) with respect to h=-g,..., g at every symbol interval within the limited range. An inverse correlation matrix calculating section (27) produces the correlation matrix Rk for the spread-spectrum sequences which respectively corresponds to the L communicators from the partial correlation matrixes and calculates the inverse correlation matrix Rk of the correlation matrix Rk. A multiplier (25) produces an estimated sequence of symbol vectors by calculating the product of the inverse correlation matrix Rk and the sequence Y of the compressed-back outputs y(k) from the register (24).

摘要： A structure of a novel spectrum spreading communication device which solves the problem with the conventional spectrum spreading communication using Barker codes, etc., and limits the rise of the side-lobe of a correlational signal independently of the order of information codes by use of a code sequence having a code length of at least 14. The spectrum spreading communication device uses a pseudo-noise code having a code length of at least 14 and a self-correlation side-lobe of not greater than 3 as a pseudo-noise code of a direct spreading communication device which uses the pseudo-noise codes whose polarities are inverted so as to deal with also digital information. Thus, even when the pseudo-noise code length is 14 or more, the side-lobe of the correlation coefficient can be restricted. Accordingly, the error rate of the spectrum spreading communication device is reduced and the processing gain is improved.
