摘要： A method for advancing or stepping back a chaotic sequence generation. The method involves selecting a plurality of polynomial equations. The method also involves selecting a value for the acc-dec variable v for advancing or stepping back a chaotic sequence generation by at least one cycle at a given time. The method further involves using residue arithmetic operations to respectively determine solutions for the polynomial equations using the acc-dec variable v. The solutions are iteratively computed and expressed as residue values. The method involves determining a series of digits in a weighted number system based on the residue values.

摘要： A method (300) for generating a sine and cosine of an input angle (∅
1O2 ). The method involves decomposing ∅
1O2 to an octant or quadrant, a coarse angle (A), and a fine angle (B), determining cos(A), and determining sin(A). The method also involves decomposing cos(A) and sin(A) to a most significant word (MSW) and a least significant word (LSW). The method further involves computing an approximation of 1-cos(B), an approximation of sin(B), and a plurality of products (P
1 ,..., P
4 ) using the MSWs and approximations. The method involves computing approximations of cos(∅'
102 ) and sin(∅'
102 ) using the values for cos(A), sin(A), and P
1 ,..., P
4 . The method involves scaling the approximations of cos(∅'
102 ) and sin(∅'
102 ) to a desired resolution.

摘要： A method is provided for correlating samples of a received signal and samples of an internally generated/stored sample sequence ("IGSSS"). The method involves performing a first iteration of a first-resolution correlation state. The first-resolution correlation state involves: selecting a first N sets of samples from the received signal; selecting a first set of samples from the IGSSS; and concurrently comparing each of the N sets of samples with the first set of samples to determine if a correlation exists between the same. If it is determined that a correlation does not exist between one of the N sets of samples and the first set of samples, then a second iteration of the first-resolution correlation state is performed. If it is determined that a correlation exists between one of the N sets of samples and the first set of samples, then a first iteration of a second-resolution correlation state is performed.

摘要： A class D amplifier includes a separating circuit for separating a pulse code modulation (PCM) signal into a K least significant bits (LSBs) signal and an L most significant bits (MSBs) signal; a PCM to pulse width modulation (PWM) converter for converting the L MSBs signal into a PWM signal; and an LSB processor for proportionally altering the PWM signal from the PCM to PWM converter based upon the K LSBs signal to define a PWM output control signal. The PCM input signal may be an N-1 bit PCM magnitude signal. The amplifier includes a sign and magnitude extraction circuit for extracting a sign bit signal and the N-1 bit magnitude signal from an N bit two's complement PCM input signal. The class D amplifier also includes a switch driver responsive to the extracted sign bit signal and the PWM output control signal, such as to control polarity and on time, respectively. The PCM to PWM converter may be one of a symmetric PCM to PWM converter; a trailing edge PCM to PWM converter; and a leading edge PCM to PWM converter.

摘要： Systems (400, 500, 600) and methods (300) for generating a chaotic amplitude modulated signal absent of cyclostationary features by preserving a constant variance. The methods involve: generating a PAM signal including pulse amplitude modulation having a periodically changing amplitude; generating a first part of a constant power envelope signal (FPCPES) by dividing the PAM signal by a square root of a magnitude of the PAM signal; generating a second part of the constant power envelope signal (SPCPES) having a magnitude equal to a square root of one minus the magnitude of the PAM signal; and generating first and second spreading sequences (FSS and SSS). The methods also involve combining the FPCPES with the FSS to generate a first product signal (FPS) and combining the SPCPES with the SSS to generate a second product signal (SPS). A constant power envelope signal is generated using the FPS and SPS.
