چکیده

We present a sector-based resource allocation scheme for broadband fixed wireless networks. For SIR requirements of about 12 to 14 dB, the scheme can deliver an effective reuse factor of one, while permitting a given spectrum to be re-used in every sector of every cell. The scheme also offers flexible sector planning, easy capacity growth, and addresses irregular cell layout and non-uniform traffic density.

A Radio Resource Allocation Scheme for Fixed Broadband Wireless Access Systems with Avoidance of Major Interferers

An improved radio resource allocation scheme with avoidance of major interferers is proposed and analyzed for the downlink of Fixed Broadband Wireless Access (FBWA) systems with full frequency reuse. The scheme is based on Enhanced Staggered Resource Allocation (ESRA) and permits the enhancement of the throughput per sector. Simulation results show a maximum downlink throughput per sector in ex...

On the Downlink Capacity of Cellular CDMA and TDMA over Nondispersive Channels

We investigate the multiuser interference on the downlink channel (from base station to users) in cellular code-division multiple access (CDMA) and time-division multiple access (TDMA) systems. The results indicate that for the same total bandwidth occupancy and maximum number of users per cell, multiuser interference is approximately 10 dB higher in CDMA in fully-loaded cells. The implication ...

Optimization models and algorithms for downlink UMTS radio planning

Abstract— The problem of planning third generation UMTS networks with a W-CDMA radio interface is investigated. In previous work [2]–[4] we have proposed discrete optimization models and algorithms for supporting the decisions on where to locate base stations and which antenna configuration to select considering quality constraints for the uplink (mobile to base station) direction. The Signal-t...

Meta Distribution of the SIR in Large-Scale Uplink and Downlink NOMA Networks

We develop an analytical framework to derive the meta distribution and moments of the conditional success probability (CSP), which is defined as success probability for a given realization of the transmitters, in large-scale co-channel uplink and downlink non-orthogonal multiple access (NOMA) networks with one NOMA cluster per cell. The moments of CSP translate to various network performance me...

Performance Evaluation of a SCM Optical Transmission System

This paper focuses on the impact of Optical Beat Interference (OBI) on the performance of subcarrier multiplexed optical transmission system for the application on radio link via optical fiber. Performance results are evaluated for QPSK modulation of Microwave subcarriers with digital NRZ coded random data patterns. A suitable bandwidth of 890 – 950 MHz is selected for subcarriers and channel b...
