    Abstract: AN METHOD AND APPARATUS FOR COMPUTING A SCALAR PROJECTION OF A VECTOR ONTO ANOTHER VECTOR. THE APPARATUS COMPRISES A MULTIPLYING CIRCUIT AND A SUMMING CIRCUIT. THE MULTIPLYING CIRCUIT IS FOR MULTIPLYING A VALUE REPRESENTATIVE OF A FIRST COMPONENT OF A FIRST VECTOR WITH A VALUE REPRESENTATIVE OF A FIRST COMPONENT OF A SECOND VECTOR TO PROVIDE A FIRST INTERMEDIATE VALUE, AND FOR MULTIPLYING A VALUE REPRESENTATIVE OF A SECOND COMPONENT OF A FIRST VECTOR WITH A VALUE REPRESENTATIVE OF A SECOND COMPONENT OF A SECOND VECTOR TO PROVIDE A SECOND INTERMEDIATE VALUE. THE SUMMING CIRCUIT SUMS THE FIRST AND SECOND INTERMEDIATE VALUES TO PROVIDE A RESUTANT VALUE REPRESENTATIVE OF THE SCALAR PROJECTION OF THE FIRST VECTOR ONTO THE SECOND VECTOR. THE APPARATUS MAY FURTHER COMPRISE A STORING CIRCUIT AND A SELECTION CIRCUIT. THE STORING CIRCUIT IS FOR STORING THE VALUES REPRESENTATIVE OF THE FIRST AND SECOND COMPONENTS OF THE FIRST VECTOR, AND THE VALUE REPRESENTATIVE OF THE FIRST AND SECOND COMPONENTS OF THE SECOND VECTOR. THE SELECTION CIRCUIT PROVIDES AN OEDERED SUPPLY OF THESE VALUES TO THE MULTIPLYING CIRCUIT.(FIG 6)

    Abstract: AN APPARATUS AND METHOD FOR ADDING AND REMOVING A TARGET BASE STATION FROM A NETWORK OF BASE STATIONS, WHICH INCLUDES BASE STATIONS ADJACENT THE TARGET BASE STATION. THE APPARATUS IS COMPRISED OF TWO ATTENUATORS: A FIRST FOR SETTING AN ARTIFICIAL RECEIVE NOISE POWER LEVEL AND A SECOND FOR SETTING A TRANSMIT LEVEL. THE TRANSMIT LEVEL DETERMINES THE FORWARD LINK COVERAGE AREA OF THE BASE STATION. THE ARTIFICIAL NOISE LEVEL SETS THE REVERSE LINK COVERAGE AREA OF THE BASE STATION. WHEN A BASE STATION IS ADDED, INITIALLY THE TRANSMIT POWER IS LOW AND THE ARTIFICIAL RECEIVE NOISE POWER IS HIGH SUCH THAT THE FORWARD AND REVERSE LINK COVERAGE AREAS ARE COLLOCATED IN CLOSE PROXIMITY TO THE BASE STATION. AS THE BASE STATION BLOSSOMS INTO FULL OPERATION, THE ARTIFICIAL RECEIVE NOISE POWER IS DECREASED AND THE TRANSMIT LEVEL IS INCREASED SUCH THAT THE TWO COVERAGE AREAS OF THE BASE STATION REMAIN BALANCED AS THE COVERAGE AREAS EXPAND. WHEN A BASE STATION IS TO BE REMOVED FROM A SYSTEM, THE SAME ATTENUATORS ARE USED TO WILT THE TWO COVERAGE AREAS IN UNISON AS THE POWER LEVEL TRANSMITTED FROM THE BASE STATION DECREASES.FIGURE 4

    Abstract: A maximal length linear sequence pseudorandom noise (PN) sequence generator for generating an augmented length PN sequence of length 2N. The PN generator includes circuitry for generating a PN sequence of length 2N -1 chips. A sequence augmenting circuit is included which inserts at least one additional chip in the PN sequence at a predetermined position within the PN sequence so as to provide an output of an augmented PN sequence of length 2N chips. The generator may also include sequence shifting circuitry which is responsive to a mask input for providing a predetermined shift in the output augmented PN sequence without incurring a transition period where the shifted output is invalid.
