摘要

如何提昇GSM系統上數據傳送的速率一直爲熱門之話題，本研究針對目前GSM架構探討高速（或多重速率）的(n-1)/n Punctured Convolutional Code應用的可能性，亦即在不改變頻寬的條件下，加快數據傳送的傳送的速率。此相同的理論亦可應用於其他數位蜂巢系統末來第三代的系統。設計的實例轉以多重模擬，並和理論性能曲比較，以找出最佳可應用之Punctured Convolutional Code。

To increase data transmission rate in GSM or even in the future third generation cellular system is in great demand. The proposed method will emphasize but not limit to the current running GSM system. We use higher n of (n-1)/n convolutional code design with puncturing technique for different rate. Multiple simulations of the designed structures justify the theoretical analysis.
