Abstract

This Paper Addresses a Performance Enhancement of Multitude Receivers Communicating with a Basestation. A General Link between Basestation and Terminal is that a Basestation is connected with Multitude Receivers and Time, Frequency and Code are shared and used among them. We propose an Algorithm of Enhancing Receiver Capability at the Receiver when access Point of Acting as a Basestation in this Environment Modifies Transmission Data Separately to be sent. In the Proposed Algorithm, we configure Transmit Data to Use Maximal Ratio Combining Technique in the Receiver, and Estimate Transmitter Signal per Each Receiver and Simulate Bit Error Rate and Show the Performance Results.

이 논문은 하나의 기지국과 통화하는 다수의 단말기에서의 수신 성능 개선에 관한 것이다. 일반적인 기지국과 단말기들간의 연결은 다수의 단말기들이 하나의 기지국에 연결되어 있으며, 시간이나 주파수 또는 코드를 할당하여 사용하는 방법이 사용되고 있다. 이러한 환경에서 기지국 역할을 하는 억세스 포인트가 여러 개의 단말기들과 별도로 전송하는 전송 데이터를 변형하여 수신기에서 수신 능력을 향상시킬 수 있는 알고리즘을 제안한다. 제안하는 알고리즘은 수신기에서 최대 율 결합을 사용할 수 있도록 송신 데이터를 구성하고, 수신기마다 송신 신호를 추정하여 비트오류율을 모의 실험하고 그 성능을 제시한다.
