Title: Scramble/descramble system/method for broadcasting data
Inventor: YAMAMOTO TETSUO
IPC: H04N7/167
Filed: 1995-08-08
Abstract: PROBLEM TO BE SOLVED: To permit a reception side to accurately recognize a scramble key to realize descramble by permitting a broadcasting-side to extract the bit string of a prescribed position from an original data packet and to generate the scramble key. SOLUTION: A key number read part 20 selectively reads only a bit in a previously decided position among inputted data blocks. Here, plural values as positions are previously decided. A master key read part 22 inputs the bit string which is read by the read part 20 as a master key number. The read part 22 is provided with ROM storing many scramble master keys identified by the master key numbers. The scramble master key corresponding to the inputted master key number is called out from ROM. The original data packet is scrambled and broadcasted by using the scramble key. Thus, it is not necessary to broadcast special scamble key identification information other than data to be broadcasted.

Title: Packet switch
Inventor: ITO ATSUO
IPC: H04L12/933
Filed: 1989-08-29
Abstract: PURPOSE:To prevent the order of packets in a switch from being inverted by using a contention arbitration bit of a packet number provided on a head of a packet so as to apply contention arbitration and using priority designation bit so as to designate the priority thereby keeping the priority before re-input. CONSTITUTION:The relative position of re-input packet is unchanged after passing through sorting networks 10, 12 and a packet inputted newly is sorted to low-order of re-input packet. Thus, even when a packet repeats passing through the sorting networks 10, 12 for many times, packets whose outgoing line number is the same always have higher priority than newly inputted packets and outputted to an outgoing line of the sorting networks 10, 12. A packet reaching a routing network 15 of the post-stage is the oldest packet with the highest priority among outputs of the sorting networks 10, 12. Thus, the sequence of packets at outgoing lines of a switch is not reversed.

Title: Method and architecture to correct carrier offset and timing offset of spread code in direct sequence spread spectrum communication system
Inventor: CHIA-CHI FAN
IPC: H04B1/7075
Filed: 1998-08-07
Abstract: PROBLEM TO BE SOLVED: To correct an offset of a carrier frequency and a timing offset of a spread code. SOLUTION: An integer part of an offset of a carrier frequency is obtained by matching a received signal with a spread code whose center frequency is located in a frequency being an integral multiple of the reciprocal of a period of the spread code and searching a spread code whose amplitude is a maximum among the matched results. A direction flag is obtained by comparing the amplitude of the searched code with the amplitude of the matched result adjacent thereto. An integer part of the offset of the carrier frequency is corrected (603), a difference between phase angles as a result of two consecutive matched codes is calculated and a fraction part of the offset of the carrier frequency is calculated (604) according to the direction flag.  After the correction of the offset of the carrier frequency, a 1st path for a channel impulse response causing a minimum delay spread is obtained and searched to correct (603) a timing offset of the spread code.
