技术资料 AP2406技术手册
The AP2406 is a 1.5Mhz constant frequency, slope compensated current mode PWM step-down converter. The device integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. It is ideal for powering portable equipment that runs from a single cell lithium- ...

论文 基于频率插值的4.0kbps 语音编码器的性能和设计(英文)
The 4.0 kbit/s speech codec described in this paper is based on a
Frequency Domain Interpolative (FDI) coding technique, which
belongs to the class of prototype waveform Interpolation (PWI)
coding techniques. The codec also has an integrated voice
activity detector (VAD) and a noise reduction capabi ...

书籍 Bandwidth-Efficient+Digital+Modulation
Traditional modulation methods adopted by space agencies for transmit-
ting telecommand and telemetry data have incorporated subcarriers as a sim-
ple means of separating different data types as well ensuring no overlap
between the radio frequency (RF) carrier and the modulated data’s frequency
spe ...
书籍 Baseband+Receiver+Algorithms
The growing interest for high data rate wireless communications over the last few decades
gave rise to the emergence of a number of wideband wireless systems. The resulting scarcity
of frequency spectrum has been forcing wireless system designers to develop methods that
will push the spectral effici ...
书籍 Broadband Wireless Networks
Emerging technologies such as WiFi and WiMAX are profoundly changing the
landscape of wireless broadband.  As  we evolve into future generation wireless
networks, a primary challenge is the support of high data rate, integrated multi-
media type traffic over a unified platform. Due to its ...
