Abstract: A transmission line coupler (115) for a transmitter output signal (123) generated by an RF signal amplifier (103) includes a through-path transmission line (201) and a coupled-path transmission line (202) electromagnetically coupled thereto by multiple serpentine-like portions (such as portions 641, 642, 643 and 644 in Fig. 6), which are disposed on opposite sides of the through-path transmission line (201) for enhancing coupling sensitivity and eliminating degradation in the amount of coupling due to variations in the transmission line plating registration. Offset portions (641, 643) on one side of the through-path transmission line (201) provide substantially the same amount of coupling as the offset portions (642, 643) on the other side of the through-path transmission line (201). The transmission line coupler (115) is embedded in the output match of the final amplifier (103) and includes complex impedances (212 and 210, 222) at each port of the coupled-path transmission line (202) for substantially eliminating undesired reflections. The coupled port of the coupled-path transmission line (202) is coupled by an inductor (211) to a hot-carrier diode (206) for enhancing the detection sensitivity thereof.

Abstract: In an adaptive CDMA receiver (20), a Direct Sequence Spread Spectrum (DS-SS) received signal and a reference signal are equalized by minimizing the error between them. The received signal includes a desired DS-SS communication signal comprising binary bits coded with spreading chip sequences. The received signal is sampled at a chip rate to produce sampled received signals which are correlated with each other. The received samples are partially de-correlated by employing an orthogonal transformation algorithm to provide de-correlated subspace elements and correlated subspace elements. The adaptive equalization process is based on de-correlated and correlated subspace elements. Tap coefficients of a despreading equalizer (400) are updated for the de-correlated and correlated elements individually and collectively, respectively. This selective updating of tap coefficients provides for fast convergence and minimum error.

Abstract: A method provides delays during memory dialing by automatically inserting pause characters within the dialing sequence based upon the user's entry of the dialing sequence. The method establishes a time-out period (64) when storing dialing sequences, and adds a pause character (66) to the dialing sequence if the time-out has expired. The method also determines whether any digit keys have been selected (68) to be stored in the sequence. Finally, the method monitors the tip and ring line of a standard telephone line to detect a far end ringing signal (76) and insert a special pause character (78). The special pause character will provide a delay until a far end pickup is detected during automatic dialing. Also, a circuit includes a keypad (20) for selecting digits to be stored; a control circuit (18) for detecting a delay between the selection of digits and generating a first pause signal in response; and a digital signal processor (30) for detecting a far end ringing signal to generate a second pause signal; and a memory device (26) for storing said digits and pause signals.
