image compression using btc algorithm. matlab program. This function accepts an image(color or GRAY) and compresses it using the block truncation coding.
ST7529液晶驅動 The ST7529 is a driver & controller LSI for 32 GRAY scale graphic dot-matrix liquid crystal display systems. It generates 255
Segment and 160 Common driver circuits. This chip is connected directly to a microprocessor, accepts Serial Peripheral
Interface (SPI), 8-bit/16-bit parallel or IIC display data and stores in an on-chip display data RAM. It performs display data
RAM read/write operation with no external operating clock to minimize power consumption. In addition, because it contains
power supply circuits necessary to drive liquid crystal, it is possible to make a display system with the fewest components.
This m-file simulates MPSK (BPSK,QPSK,8PSK)with theoretical and simulated results using GRAY coding. Numerical examples of a satellite link design are shown using QPSK and/or 8PSK when the bit rate(Rb)is greater than the channel bandwidth Wc (Band-limited channel).
