摘要： A method and apparatus provide for soft handoff operation of at least a first signal transmitted according to a first communication standard (IS-95B) and a second signal transmitted according to a second communication standard (IS-95C). A mobile station (104) initially receives the first signal, detects presence of a pilot signal, measures pilot signal strength, transmits a pilot strength measurement message, fails to receive a handoff direction message after transmitting the pilot strength measurement message, searches for detecting presence of a broadcast control channel associated with the type IS-95C cell sites, measures a carrier to interference ratio of the broadcast control channel, compares the carrier to interference ratio to a threshold, if the carrier to interference ratio is above the threshold, initiates a second communication according to IS-95C standard, thus, allowing initiating a soft handoff operation by allowing the base sites to transmit information according to the IS-95B and IS-95C standards respectively via the first and second signals. MS 104 combines the first and second signals to take advantage of the soft hand-off operation.

摘要： A method and apparatus for reuse of pseudo-random noise (PN) offsets within a cell of a wireless communication system such as a multi-sector CDMA system. Adaptive antenna arrays are employed to form the multiple sector areas within the CDMA cell. A forward link data channel is established between a mobile unit and a base station via sectors that share or reuse comment PN offsets, thereby providing desirable transmit diversity.

摘要： A current mode of operation is provided to a Walsh spreader (203), and based on the current mode of operation, the Walsh spreader (203) either varies a Walsh code at a symbol rate, or holds the Walsh code constant. During multi-carrier transmission a first symbol within a data stream (210) is spread with a first Walsh code, while symbols immediately preceding and following the first symbol are spread by a another, differing Walsh code. The sequence of Walsh codes exiting the spreader (201) is further scrambled by a pair of Pseudo-Noise (PN) codes (224) that are held constant for three Walsh code periods during multi-carrier transmission, and are not held constant during direct-spread transmission.

摘要： In a hybrid matrix amplifier array (100), the amplitude of each of a plurality of input signals is measured (132-136, 202). In response to the signal amplitude measurements, an overload condition that will result in an amplifier overload in said hybrid matrix amplifier array is estimated (204, 206, 138). In response to the estimation of the overload condition, the signal amplitude of at least one of the plurality of input signals is modified to prevent the overload condition in the hybrid matrix amplifier array. An overload condition may be estimated if the sum of the amplitudes of the input signals exceeds a threshold (206). In one embodiment, all input signals are modified by proportionately reducing the amplitude of each of the plurality of input signals (304).

摘要： A transmitter (300) comprises summers (301-307, 3178-319), and mixers (309-315, 333). During multi-carrier transmission, multiple I and Q components enter the transmitter. I.sub.1 is summed with I.sub.3, Q.sub.3 is subtracted from Q.sub.1, Q.sub.1 is added to Q.sub.3, and I.sub.3 is subtracted from I.sub.1. The outputs of a first and a second summer (301, 305) enters a first and a second mixer (309, 313) where they are mixed by a cosine function. Similarly, the outputs of a third and a fourth summer (303, 307) enter a third and a fourth mixer (311, 315) where they are mixed by a sine function. The output from first and the second mixer (309, 311) enter a first summer (317) where they are summed along with the I.sub.2 component. The output from the third and the fourth mixer (313, 315) enters a second summer (319) where they are summed along with the Q.sub.2 component.
