Multirate transmission in frequency-hopping multicarrier direct sequence code division multiple access systems

چکیده
| Against the back-cloth of the explosive expansion of the Internet and the continued dramatic increase in demand for high-speed multimedia wireless services, there is an urging demand for exible, broadband transceivers. A versatile broadband multiple access scheme, combining frequency-hopping (FH) with multicarrier DSCDMA (FH/MC DS-CDMA) is proposed and investigated. The FH/MC DS-CDMA scheme is capable of meeting the requirements of future mobile wireless systems, while also ensuring compatibility with the existing 2ndand 3rdgeneration systems in the context of multirate transmission.

Slow frequency-hopping multicarrier DS-CDMA for transmission over Nakagami multipath fading channels
A novel multiple access scheme based on slow frequency hopping multicarrier direct-sequence code division multiple access (SFH/MC DS-CDMA) is proposed and investigated, which can be rendered compatible with the existing second-generation narrowband CDMA and third-generation wideband CDMA systems. The frequency hopping patterns are controlled by a set of constant-weight codes. Consequently, mult...
متن کاملSensitivity of Multicarrier Systems to Synchronization Errors
In this contribution, we give an overview of the sensitivity of a number of multicarrier systems to carrier and symbol synchronization errors. A comparison is made between orthogonal frequency-division multiplexing/multiple access (OFDM(A)) and two combinations of the orthogonal multicarrier (MC) transmission technique with the code-division multiple access technique (CDMA), i.e. multicarrier C...

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 CDMA with Adaptive Frequency Hopping for Mobile Radio Systems
A modified multicarrier (MC) direct-sequence code-division multiple-access (DS-CDMA) system has been proposed for use over slow multipath fading channels with frequency selectivity in the reverse link transmission of a cellular network. Instead of transmitting data substreams uniformly through sub-channels, data substreams hop over subchannels with the hopping patterns adaptively adjusted to th...
