常見例句

• When decoding a HARQ retransmission packet, the system usually combines error packet and discards its LLR.
  HARQ譯碼時,一般只保留錯誤分組,丟棄錯誤分組的輸出LLR值。
• Compared with initial Degree Distribution Based HARQ (DDB-HARQ) scheme, this scheme improves system performance such as bit error rate and throughput.
  與原始的基于度分布的HARQ方案相比，該方案使系統(tǒng)的誤比特率和吞吐量指標(biāo)得到了明顯改善。
• For HARQ, hop-by-hop and edge-to-edge methods are used;for ARQ, besides edge-to-edge and hop-by-hop, the last hop guarantee mechanism is also applied.
  其中針對HARQ提出了逐跳和端到端兩種方法，而對于ARQ功能除了逐跳和端到端兩種方法外還增加了最后一跳的保障機(jī)制。
• The reliability of data transmission in wirless communication system is improved using HARQ scheme with Automatic Repest Request(ARQ) and Forward Error Correction(FEC).
  為了使無線通信系統(tǒng)中數(shù)據(jù)的傳輸快速可靠,需要采用自動重發(fā)請求(ARQ)和前向糾錯碼(FEC)相結(jié)合的混合自動重發(fā)請求(HARQ)技術(shù)。
• The optimization of mapping rule in hybrid ARQ(HARQ) protocol of high speed downlink packet access(HSDPA) system is presented,especially for full incremental redundancy(FIR) and partial incremental redundancy(PIR) with high rate Turbo code.
  針對高速下行分組接入(HSDPA)系統(tǒng)中的混合重傳(HARQ)協(xié)議;提出適用于高碼率Turbo碼的全增余(FIR)和部分增余(PIR)型的映射準(zhǔn)則優(yōu)化方法.
• In fading and shadowing channels,error control techniques are used for the reliable transmission. As a combination of forward error correction and automatic repeat request(ARQ),Hybrid ARQ(HARQ) protocol provides both of the advantages.
  為了保證數(shù)據(jù)在無線衰落信道條件下的可靠傳輸,產(chǎn)生了聯(lián)合前向糾錯編碼(FEC)與自動請求重傳(ARQ)的混合ARQ(HARQ)技術(shù)。
