Abstract

The invention provides a system for correcting a transmission channel with high series, which consists of a data memory used for storing a channel parameter, a corrector rotation unit used for carrying out rotating operation to obtain an adjustment coefficient of the corrector, a pre-filter rotation unit used for carrying out rotating operation to obtain the adjustment coefficient of the pre-filter and a counting judgment unit used for calculating and judging times of the rotation and a row shift. The system of the invention can reduce calculating cost for determining a single coefficient and allow the current filter and corrector to be used for correcting the transmission channel with high series.

Description

technical field

[0001] The invention relates to a correction system including a filter and a corrector in the process of receiving data. Background technique

[0002] The transmission channel model between the sender S and the receiver R in the communication system, such as figure 1 As shown, the sender S will send data or send a signal S k After having channel coefficient h k The transmission channel H is output to the model adder, and a noise signal n is input to the adder k , the aforementioned two signals are input to the receiver R at the same time. Among them, the noise signal n k is additional with variable Οƒ n 2 The white Gaussian noise of , and the white Gaussian noise and the transmitted signal S k is irrelevant.

[0003] Then, the signal X received by the receiver R k can be expressed by the following formula, namely

[0004] X k = Ξ£ i = 0 ...
