"Channel capacity" and the "throughput" Analysis
Channel capacity is the maximum mutual information. Specifically, the channel capacity is in a certain bandwidth and signal to noise ratio, it can be implemented by means of an encoding for error-free transmission reached at the maximum information transmission rate , in units of bit / s, which is an upper bound, in practical applications , the transmission rate is less than equal to the channel capacity. Channel capacity considering mainly the object examined actual physical channel capacity of transmitting information, not for a specific codec scheme and transmission technology.
And Throughput refers to the number of information bits correctly transmitted in a unit time system , the unit is' bit / s (can also be Byte / s or packet / s measured), is not an upper bound. If a certain coding scheme is introduced, then in calculating the throughput, we must take the redundant bits (e.g., parity bits) is removed. Further, throughput is more focused on the system level, for example, the throughput of a cell. Throughput is examined actual transmission level information in the network (link), the main consideration is the object transmission technology (e.g., access mode, multiplex mode; duplex mode, collaboration, etc.).
Channel capacity is the signal of the maximum transmission rate at different transmission modulation scheme that can be carried, the throughput of the terminal (or line) the actual signal transmission rate , channel capacity is the maximum rate the theoretical channel transmission data, the throughput of the current in such a the actual transmission rate of the channel is actually reach the ideal value.Throughput is generally greater than the channel capacity。
