Abstract. Orthogonal Variable Spreading Factor (OVSF) code assignment is a fundamental problem in Wideband Code-Division MultipleAccess (W-CDMA) systems, which play an important ro...
We propose a parallel and modular architecture well suited to 802.16e WiMax LDPC code decoding. The proposed design is fully compliant with all the code classes defined by the Wi...
—We analyse mobile propagation channels which occur in the context of car-to-car communications in the 24 GHz ISM band. From the information gathered, we design robust frame desi...
