Millimeter-wave (mmWave) communications are highly focused as a powerful mean enabling to perform very high data transmission. However it has several inherent shortcomings like directional transmission and serious attenuation in atmosphere. So it is difficult to implement random access in mmWave WLANs. In this paper, a heterogeneous control and data sub-network architecture is presented, which decouples...
SPEEX is a flexible codec based on the Code Excited Linear Prediction (CELP) algorithm and supports a wide range of speech quality. In this paper, several high-level and low-level optimization techniques have been concurrently employed to reduce the MIPS count and complexity of the SPEEX decoder in order to achieve good speech quality on an embedded DSP receiver. We reassign the decoder's stack and...
