Heat dissipation is assumed to be one of the major challenges in the promising 3D integration technology. Very fine grain structures like TSVs and μ-bumps have considerable impact on heat dissipation properties. However, properly considering individual details of multi-length scale systems is still a challenge for efficient system-level thermal(More)
We investigate rotated Walsh-Hadamard spreading matrices for a coded MC-CDMA system in the synchronous downlink with robust channel estimation. Rotated Walsh-Hadamard spreading sequences increase the signal space diversity. The signal space diversity improves the performance in frequency and time selective fading channels. The Hamming distance of the(More)
