笔直的公路尽头,远远望见一片辽阔的工业园区长隆方面称,引进虎鲸主要用于保护、繁育和科普教育上一页(一)要有步骤地推进完善人民币汇率形成机制改革 在人民币汇率改革之前,由于人民币汇率低估,导致国内外商品价格的扭曲,出口商品价格低廉,进口商品价格高昂,致使我国在过去很长一段时间内,出口额不断攀升,贸易赢余不断增加,连年持续出现巨额贸易顺差,引起了与贸易伙伴之间的频频贸易摩擦

实战派.....................\...\MapTileInfo.binThe first scrambler SCR1 repetitively generates a pseudo-random sequence of 4 bits, marked 0, 1, 2 and 3 in FIG. 2. The repetitively generated pseudo-random sequence of 4 bits constitutes a first pseudo-random bit sequence PRBS1 at the output of the first scrambler SCR1. This first pseudo-random bit sequence PRBS1 has to be encapsulated in multi-carrier data symbols wherein 8 bits can be embedded to constitute a first pseudo-random sequence of multi-carrier data symbols PRMS1. These multi-carrier data symbols are referred to by DMT0, DMT1 and DMT2 in FIG. 2. Because the length N (8 bits) of the multi-carrier data symbols DMT0, DMT1 and DMT2 is twice the length L (4 bits) of the pseudo-random sequence of bits that is repetitively generated by the first scrambler SCR1, each multi-carrier data symbol would contain exactly the same pseudo-random sequence of 8 bits if the first pseudo-random bit sequence PRBS1 would be encapsulated straightforwardly into the multi-carrier data symbols DMT0, DMT1 and DMT2. As a consequence, the randomness of the first pseudo-random sequence of multi-carrier data symbols PRMS1 would be inexistent. For this reason, the first divider DIV1 divides the first pseudo-random bit sequence PRBS1 into strings of N′=9 bits. Only the first 8 bits of each string of 9 bits are embedded into a multi-carrier data symbol by the first embedder EMB1, whereas the ninth bit of each string at the output of the first divider DIV1 is not used by the first embedder EMB1. The division of the first pseudo-random bit sequence PRBS1 into strings of 9 bits and the embedding into the multi-carrier data symbols DMT0, DMT1 and DMT2 is illustrated by FIG. 2. In this way, the first embedder EMB1 generates at its output the first pseudo-random sequence of multi-carrier data symbols PRMS1, that is transmitted by the transmitting circuitry TX over the telephone line CHANNEL to the VDSL receiver MC-RX at the customer premises. The length N′ of the strings created by the first divider DIV1, is chosen by the selector SEL and provided as a control signal to the first divider DIV1 in the first pseudo-random sequence generator PR-GEN1. In addition the selector SEL supplies the value N′=9 to the communicating circuitry COM which communicates this value N′ via the transmitting circuitry TX to the VDSL receiver MC-RX at the customer premises. To communicate the value N′, this value may be embedded in a thereto standardized field or message of the initialization protocol.
