摘要： A matched filter circuit for mobile communications is disclosed. The circuit may be fabricated in a small size using large-scale integration and can perform high-speed processing and double sampling at a reduced rate of power consumption. In one embodiment, a plurality of sampling and holding circuits each including a switch are divided into two groups. A control circuit successively closes one of the switches in the first group every chip time, while successively closing one of the switches in the second group at a timing shifted by one-half chip time from that of the first group, thereby enabling a double-sampling operation. Outputs of the sampling and holding circuits in each group are summed by an analog circuit with a high degree of linearity, resulting in a high processing speed combined with a reduced circuit size and power consumption.

摘要： The present invention realizes a rapid and efficient cell search and small-size instrument for an asynchronous DS-CDMA cellular system. This cell search detects the correlation between the received signal and the short code of the control channel, and matched filter 22 detects the maximum electric power correlation peak location. Next, using correlators 28-1 to 28-n which are parallelly set in a plurality for RAKE processing with plurality, identifies the long code that is set in the system with the detected long code timing. After the long code is synchronized, a multipath signal is received using 28-1 to 28-n, and the data is judged by RAKE processing. When peripheral cell search is executed, after long code timing is detected by using matched filter 22, the long code of the candidate peripheral cell is designated using the same matched filter. Handover is safely realized by receiving the signal from the connected base station by correlators 28-1 to 28-n, and the base station signal through handover by 22.

摘要： A matched filter contains a plurality of auxiliary sampling and holding circuits in addition to a main sampling and holding circuit containing multiple unit sampling and holding circuits. An auxiliary sampling and holding circuit is used to hold an input voltage, which would ordinarily be held by a unit sampling and holding circuit, when the unit sampling and holding circuit is being refreshed. By holding a part of the analog input voltage in the auxiliary sampling and holding circuits, refreshing is performed without decreasing the overall calculation speed.

摘要： An image processing method for thinning lines converts pixels having a density of a configuration to a background density. Pixels are converted according to conditions which include densities of pixels in a neighborhood around a pixel to be processed. Pixels to be converted to the background density are first converted to an index value. Subsequent pixels are evaluated using the index values of adjacent, previously evaluated pixels. Index values are then converted to the background density.

摘要： A system and method for solving adaptation problems including a neural network having multiple neurons. Each neuron includes outputs that are input to every other neuron excepting itself, and a cost calculation portion for calculating cost based on a formula that uses outputs from each neuron as variables with respect to the given adaptation problem. Adaptation problems are solved by i) randomly setting a coupling weight for each neuron based on other neuron operations and an output of each neuron in the initial state, ii) calculating a net value with respect to at least one neuron, iii) calculating cost by transmitting the output of each neuron after the net value calculation to the cost calculation portion, iv) simultaneously feeding back the difference between the cost before and after the net calculation to a neural network of mutual connection, v) correcting the coupling weight of at least one neuron according to the difference, and repeatedly changing the state of the neural network until a predetermined condition is established, and vi) changing the state of the neural network after the predetermined condition is satisfied, realizing the solution to the adaptation problem based on the output of each neuron. It is unnecessary to determine the coupling weight of synapse preliminarily when using the present invention. The present invention can solve adaptation problems having various cost functions to which conventional models cannot be applied.
