摘要： Space time transmit diversity (9, 14, 17, 19) is applied at the block level to an original block of bits (12) in order to reduce the effects of fading in wireless communication systems that use nonlinear modulation schemes (13, 33). At the receiving end, fading parameters (α1, α2) are estimated (αE1, αE2) and the properties of complex conjugates are utilized (28, 29, 201, 202) to produce a result (r1, r2) that is representative of the original block of bits.

摘要： Embodiments of the invention provide an interleaver design and header fields for ITU-T G.hnem. The header may comprise two parts that are separately encoded. A common header segment is encoded alone, and an embedded header segment is encoded with payload data. The interleaver operates on blocks having a size based upon a total number of input bits in an FEC codeword block, a total number of bits loaded on symbols that span a half mains cycle, or a maximum fragment size of 3072 bits. The blocks may be repeated before interleaving. Each block and its repetitions may be interleaved together, such as for header data, or each block and repetition may be interleaved separately, such as for payload data. Cyclic padding may be used on each block to create an integer number of symbols for transmission.

摘要： Embodiments of the invention provide time-domain link adaptation in power line communications. In one embodiment, the cyclic prefix length and position is adjusted with an OFDM symbol to overlap a periodic impulse noise pulse, thereby allowing the data carried in the symbol to be detected at a receiver. The cyclic prefix may be adjusted to provide a pattern that yields an integer number of OFDM symbols in one zero crossing period. The data rate used for the symbols overlapping the zero-crossing period may be zero or very low. A high data rate may be used for symbols outside the zero-crossing period because those symbols will not be affected by the periodic impulse noise.
摘要翻译：本发明的实施例提供了电力线通信中的时域链路自适应。在一个实施例中，循环前缀长度和位置用OFDM符号调整以与周期性脉冲噪声脉冲重叠，从而允许在接收器处检测符号中携带的数据。可以调整循环前缀以提供在一个零交叉周期中产生整数个OFDM符号的模式。用于与过零周期重叠的符号的数据速率可以为零或非常低。由于这些符号不受周期脉冲噪声的影响，因此高数据速率可用于过零周期以外的符号。

摘要： Apparatus and method for accessing a wireless telecommunications network by transmitting a random access signal. The random access signal includes a cyclic prefix signal and a guard interval. The cyclic prefix signal and the guard interval are adapted to optimize random access channel coverage in a telecommunications cell. The disclosed method for transmitting a random access signal includes transmitting a cyclic prefix signal. The duration of the cyclic prefix signal is approximately the sum of a maximum round trip delay duration of the telecommunications cell and a maximum delay spread duration. The method further includes providing a guard interval. The guard interval duration being approximately the duration of the maximum round trip delay of the telecommunications cell.

A plurality of cotemporaneous orthogonal excitation signals (S1(t), S2(t) . . . Sn(t)) are simultaneously driven onto the row conductors, respectively.

Receiver circuitry (50) includes a sense amplifier (21-1) coupled to generate an amplifier output signal (r1(t)) in response to signals capacitively coupled onto the column conductor. WHT-based circuitry (35) determines amounts of signal contribution capacitively coupled by each of the excitation signals, respectively, to the amplifier output signal.
