Effect of Spreading Bandwidth on DS-CDMA Reverse Link Capacity
نویسنده
چکیده
This paper addresses an important issue on the spreading bandwidth of direct sequence code division multiple access (DS-CDMA) cellular mobile radio systems: does wider spreading bandwidth provide larger capacity? And if so, to what extent? The capacity of the perfect power controlled reverse link is evaluated by computer simulation for 1.25MHz and 5MHz spreading bandwidths under various sets of propagation channel parameters (path loss decay factor, shadowing standard deviation, shadowing correlation, number of resolved propagation paths) and antenna diversity reception. key words: DS-CDMA, mobile radio, capacity, spreading band-

Link Capacity and Signal Power According to Allocations of Spreading Codes and Bandwidth in CDMA Systems
Reverse link performance analysis in singlecode and multi-code CDMA systems is presented. Results show that the single-code system yields better performance than does the multi-code system in terms of link capacity and signal power. This improvement increases as spreading bandwidth is reduced and the number of spreading codes assigned to a user is increased. key words: link capacity, signal pow...
متن کاملReverse Link Capacity of Orthogonal Multi-Code DS-CDMA with Multiple Connections
DS-CDMA provides a flexible support for the low-to-high bit rate of multimedia services upon a specific user’s request. A simple capacity expression is derived for a powercontrolled reverse link of orthogonal multi-code DS-CDMA with multiple connections. It is found that an orthogonal multi-code user having multiple connections is equivalent to a single connection user, but with a spreading fac...

This paper proposes broadband packet wireless access employing Variable Spreading Factor-Orthogonal Frequency and Code Division Multiplexing (VSF-OFCDM) with two-dimensional spreading that prioritizes time domain spreading in the forward link and Multi-carrier/DS-CDMA (MC/DSCDMA) in the reverse link for the system beyond IMT-2000. Based on the wireless access scheme, we propose major radio air ...
متن کاملPerformance of very low rate channel coding in W-CDMA reverse link
This paper investigates the packet error rate (PER) and the throughput performance employing code spreading (CS), in which a very low-rate channel coding is used instead of spreading by the Walsh-Hadamard channelization code, associated with Type-I Hybrid ARQ with packet combing (i.e., Chase combining) in the W-CDMA reverse link. Simulation results elucidate that the required average received s...
