For making the goal of the invention of the present invention, feature, the advantage can be the most obvious and understandable, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, the embodiments described below are only a part of embodiment of the present invention, and not all embodiments.Based on the embodiment in the present invention, the every other embodiment that those skilled in the art is obtained, broadly fall into the scope of protection of the invention.
Embodiment one
A kind of method representing data length that the embodiment of the present invention provides, as it is shown in figure 1, include:
101, the available bits in very high-throughput signaling B is obtained.
In embodiments of the present invention, the code modulation mode that very high-throughput signaling B is used for the length and these data representing data, the available bits of limited acquisition very high-throughput signaling B, in actual applications, using bit that very high-throughput signaling B can use as available bits, in the embodiment of the present invention, the available bits of very high-throughput signaling B is tail bit, tail bit is filled with zero in the prior art, so that delay register being made zero after to very high-throughput signaling B end-of-encode, coding for next time, and tail bit is used as available bits by the embodiment of the present invention.
102, the available bits of very high-throughput signaling B and count bits join together to represent the length of data.
In the embodiment of the present invention, the available bits of very high-throughput signaling B and count bits joining together to represent the length of data, its process diagrammatically is demonstrated out.As shown in Figure 2, for very high-throughput signaling B, illustrate as a example by very high-throughput signaling B of totally 9 in the present embodiment, but in actual applications, for use bandwidth 40MHz the total length of very high-throughput signaling B be 27 bits, being wherein 17 bits for representing the count bits of length of data, this sentences 9 simply citings.Wherein, the 1st and the 2nd is available bits, and the 3rd and the 4th is the bit used, the 5th, the 6th, the 7th, the 8th, the 9th count bits being to be used for representing the length of data.For prior art, only count bits is used to indicate that the length of data, and in embodiments of the present invention, also available bits is joined together represent the length of data except using count bits to be used in addition to, is provided commonly for representing the length of data.It should be noted that, the very available bits of high-throughput signaling B is tail bit, tail bit is filled with zero in the prior art, so that delay register being made zero after to very high-throughput signaling B end-of-encode, coding for next time, and tail bit is used as available bits by the embodiment of the present invention, and join together to represent the length of data with count bits.As shown in Figure 2, only the 5th, the 6th, the 7th, the 8th, the 9th length being used for representing data for prior art, a length of the 10110 of the data that in Fig. 2, count bits represents, but in the embodiment of the present invention, the mode of the length of data is represented by using count bits and available bits to join together, such as Fig. 2, it is provided commonly for representing the length of data, a length of the 1110110 of the data stated by the 1st, the 2nd, the 5th, the 6th, the 7th, the 8th, the 9th.
It should be noted that, available bits and count bits join together to represent the length of data in embodiments of the present invention, need appointment to use which bit and represent high-order, which bit represents low level, this has only to appoint between coding side and decoding end, encoding according to the high-order low level of agreement when coding side encodes, decoding end decodes according to the high-order low level of same agreement when decoding.Optionally, a kind of attainable mode is, available bits as a high position, count bits as low level, is joined together to represent the product degree of data by available bits and count bits by coding side.Such as shown in Fig. 2, with available bits that is the 1st, the 2nd represent high-order, with count bits the 5th, the 6th, the 7th, the 8th, the 9th represent that low level, mutual association get up the length for representing data.
