چکیده
In this paper, we propose new channel access mechanism for effective transmission of signal and data in IMT2000 W-CDMA system proposed by NTT DoCoMo. In proposed mechanism, base station broadcasts channel status information to prevent mobile station . from unnecessary transmission collision. That is, proposed mechanism uses competition mechanism for the transmission of first radio frame and utilizes reservation mechanism for the transmission of other following continuous radio frame. According to performance analysis, proposed mechanism has better performance than slottedALOHA because of using contention and reservation in the case that signal and data messages are transmitted.

Throughput Improvement of STS-Based MC DS-CDMA System with Variable Spreading Factor
The throughput enhancement of Space-Time Spreading (STS)-based Multicarrier Direct Sequence Code Division Multiple Access (MC DS-CDMA) system is investigated in this paper. Variable Spreading Factor (VSF) is utilized to improve the data throughput of the system. In this contribution, an analytical approach is proposed to compute a new expression for the Bit Error Rate (BER) performance of t...
متن کاملA Bandwidth Guaranteed Multi-Access Protocol for WDM Local Networks
| In this paper, we propose a bandwidth guaranteed multi-access protocol for broadcast-and-select WDM local networks with a star topology. The proposed protocol is based on a combination of contention and reservation mechanisms for time slotted WDM networks. Every node accesses the data channel by transmitting request packets in minislots on a separate control channel. There are two types of mi...

In this paper, we propose smart step closed-loop power control (SSPC) algorithm and base station assignment based on minimizing the transmitter power (BSAMTP) technique in a direct sequence-code division multiple access (DS-CDMA) receiver in the presence of frequency-selective Rayleigh fading. This receiver consists of three stages. In the first stage, with conjugate gradient (CG) adaptive ...

Transmission opportunity limit and contention window are two influenced parameters in accessing the media in the networks based IEEE 802.11e standard. In these networks, every wireless station by setting of its contention window value, determines the chance of access to wireless media. Furthermore, a transmission opportunity limit provides a period of transmission without contact for a station....

In this paper, we propose a novel slotted Dual-Channel Reservation (DCR) MAC protocol that uses 802.11 primitives for providing both Quality of Service (QoS) and fairness. RTS/CTS handshaking is transmitted on a separated control channel to prevent successive collisions of RTS and CTS packets with existing data transmission. Furthermore, contention for channel access may be initiated by sender ...
