Cross-Layer Designs of Multicarrier
نویسندگان
چکیده
− We study the performance of Non-Collision Packet Reservation Multiple Access (NC-PRMA) scheme as a MAC protocol for powerline communication networks. A PHY-MAC cross layer design is considered in order to provide Quality of Service (QoS) guarantees for integrated voice, data and video services. System performance is evaluated via simulations in terms of packet dropping probability and mean access delay.

Cross-Layer Resource Allocation for Variable Bit Rate Multiclass Services in a Multirate Multicarrier DS-CDMA Network
An approximate analytical formulation of the resource allocation problem for handling variable bit rate multiclass services in a cellular round-robin carrier-hopping multirate multicarrier direct-sequence code-division multiple-access (MC-DS-CDMA) system is presented. In this paper, all grade-of-service (GoS) or quality-of-service (QoS) requirements at the connection level, packet level, and li...
متن کاملMulticarrier Equalization: Unification and Evaluation. Part I: Optimal Designs
Equalization is crucial in mitigating inter-carrier and inter-symbol interference. To ease equalization in a multicarrier system, a cyclic prefix (CP) is typically inserted between successive symbols. When the channel order exceeds the CP length, equalization can be accomplished via a time-domain equalizer (TEQ), which is a finite impulse response (FIR) filter. The TEQ is placed in cascade with...
متن کاملHigher Data Rates in GSM / EDGE with Multicarrier
One of the potential future development areas in the GSM/EDGE standard is the increase of user peak transfer rates. For a wide area coverage system like GSM/EDGE, the design of higher data rate scheme can be based on the transmission on multiple carriers, instead of one single carrier. This work evaluates the feasibility of a multicarrier concept in GSM/EDGE and aims at minimizing modifications...
