The Valgrind distribution has multiple tools. The most popular is the memory checking tool (called Memcheck) which can detect many common memory errors such as: * touching memory you shouldn t (eg. overrunning heap BLOCK boundaries) * using values before they have been initialized * incorrect freeing of memory, such as double-freeing heap BLOCKs * memory leaks.

This a software runing on the matlab, it is used in the channel coding simulation. It include DVB-S2 LDPC, Covolution turbo, and BLOCK turbo code, You can choose which channel coding to run. it run the encoder and add white noise in the channel, then it run the decoder, and compute the error rate.

USB海量存儲設備類規(guī)范包括四個獨立的子類規(guī)范：(ATA command的那個沒有) ①USB Mass Storgage Class Control/Bulk/Interrupt(CBI)Transport ②USB Mass Storage Class Bulk-Only Transport ③USB Mass Storage Class ATA Command BLOCK ④USB Mass Stroage Class UFI Command Specification。 前兩個子規(guī)范定義了數(shù)據(jù)/命令/狀態(tài)在USB上的傳輸方法。 Bulk-Only傳輸規(guī)范僅僅使用Bulk端點傳送數(shù)據(jù)/命令/狀態(tài)， CBI傳輸規(guī)范則使用Control/Bulk/Interrupt三種類型的端點進行數(shù)據(jù)/命令/狀態(tài)傳送。 后兩個子規(guī)范定義了對存儲介質(zhì)的操作命令。 ATA 命令規(guī)范用于硬盤。 UFI命令規(guī)范是針對USB移動存儲而制定的，實際上UFI命令格式是基于SFF-8070i和SCSI-2規(guī)范，總共定義了19個12字節(jié)長度的操作命令。

This paper investigates the design of joint frequency offset and carrier phase estimation of a multi-frequency time division multiple access (MF-TDMA) demodulator that is applied to a digital video broadcasting—return channel system via satellite (DVB-RCS). The proposed joint estimation algorithm is based on the interpolation technique for two correlation values in the frequency and phase domains. This simple interpolation technique can significantly improve frequency and phase resolution capabilities of the proposed technique without increasing the number of the correlation values. In addition, the overall BLOCK diagram of a digital communications receiver for DVB-RCS is presented, which was designed using the proposed estimation algorithms. Index Terms—Carrier phase estimation, DVB-RCS, frequency offset estimation, interpolation, joint estimation, MF-TDMA.
