This paper describes a method developed for gender identification that combines first three formants, pitch period, and the energy between each adjacent pair of formants. The information provided by the energy, formants, and pitch estimation is combined using a classifier to identify the gender of the speaker. All the parameters are determined for a voiced part of the speech samples. We used five...
Next generation wireless systems, such as the IEEE 802.16e specification, are designed to provide great flexibility in scheduling radio resources on a per frame basis. Such flexibility, coupled with the need to maintain good quality of service (QoS) for cell-edge users can, however, lead to significant control channel overhead especially when using low code rates to maintain cell edge coverage. It...
In this paper, the performance of a prototypical IEEE 802.16e network is analyzed via link and system simulations. The exponential effective SIR mapping (EESM) is used to map the instantaneous SINR of received signals to a service-specific packet erasure rate (PER), which is in turn used to assess the downlink and uplink network and user data throughput. A variety of data traffic models are considered,...
