Description

Signal transmitting method and device

The present application claims priority to Chinese Patent Application Serial No. JP-A-----------

Technical field

The present disclosure relates to the field of Digital Subscriber Line (DSL) technology, for example, to a signal transmission method and apparatus.

Background technique

Maximum Ratio Transmission (MRT) technology was proposed by BT in the ITU-T proposal in September 2016. It is a method to effectively utilize the idle pair in the vector group to obtain the spatial diversity gain. The principle of MRT is to convert the strong crosstalk between channels into the received signal-to-noise ratio (SNR) gain of a specified customer terminal equipment (CPE) through precoding diversity at the transmitting end. Rate boosting.

Assuming that there are N twisted pairs and K active users (number of CPEs) in a vector group, FIG. 1 is a schematic diagram of a simplified use case of a vector group in the related art, as shown in FIG. 1 , N=8 and K=2 in the vector group. That includes two active CPEs and six idle lines,

lines

2, 3, and 5 are set to support CPE_2, and other lines in the group are set to support CPE_4.

H _sub denotes a channel matrix of (K*N), the signal r is a column vector of (K*1) received by K active users, and s is a column vector of (N*1). H _k,n denotes a channel that is sent from the distributed processing unit (DPU) port n and received by CPE_k. among them,

r=H _sub s+n.

Through a (N*K) precoding matrix P _sub , such that s=P _sub x, x represents the symbol to be transmitted, is the column vector of (K*1), and the CPE can obtain vectoring than the N lines. Higher SNR.

If all N twisted pairs can support the kth CPE (such as K=1), the equivalent channel path is the kth line of H, marked as

To maximize the SNR to increase the rate, configure the precoder as a column vector.

μ is a normalization factor, and precoding symbols from different transmitters are coherently accumulated, and the received signal of the kth active CPE is derived.

If K>1, such as K=2, it belongs to the case of group-MRC. The i-th column of H _sub represents the channel path from the ith transmitter. There is only one target receiver for each transmitter. That is, there is only one CPE in each group. In order to eliminate crosstalk between activated users, it is necessary to satisfy H _sub P _sub = D, and D is a diagonal matrix of (K*K).

Therefore, the related MRT technology, although utilizing the idle DPU transmit port, does not utilize the idle CPE receive port.
