The performance of space–time trellis codes (STTCs) serially concatenated with convolutional codes and Bose–Chaudhuri–Hocquenghem codes is evaluated over quasistatic Rayleigh fading channels. The STTCs are used as inner codes since they provide diversity owing to their multi-antenna nature. The loss in spectral efficiency incurred due to the added(More)
Electricity cost constitutes a significant fraction of the total operations costs in a cellular network. We present Low-Carb, a practical scheme which reduces the power consumption in such networks. Low-Carb achieves this by coupling Base Transceiver Station (BTS) power savings with Call hand-off—two features widely available to cellular operators.(More)
