Устройство связи, выполненное для использования с сигналом связи, имеющим специальную преамбулу, которая предусматривает повышенную эффективность использования полосы пропускания, причем устройство связи содержит ! первое устройство, выполненное с возможностью манипулирования сигналом поблочной передачи, имеющим размер блока, равный N, где N представляет собой целое число, большее 1; ! причем сигнал поблочной передачи имеет преамбулу с конфигурацией символа, так что каждый из, по меньшей мере, одного символа из всех символов преамбулы может использоваться для всех этапов из оценки смещения частоты, тактовой синхронизации и оценки канала. ! 2. Устройство связи по п.1, в котором сигнал поблочной передачи имеет преамбулу с конфигурацией символа, так что каждый из по меньшей мере 50% всех символов преамбулы может использоваться для всех этапов из оценки смещения частоты, тактовой синхронизации и оценки канала. ! 3. Устройство связи по п.2, в котором сигнал поблочной передачи имеет преамбулу с конфигурацией символа, так что каждый из по существу всех символов преамбулы может использоваться для по меньшей мере двух этапов из оценки смещения частоты, тактовой синхронизации и оценки канала. ! 4. Устройство связи по п.1, в котором преамбула является циклически ортогональной. ! 5. Устройство связи по п.4, в котором использования преамбулы не имеют дополнения нулями или не имеют циклический префикс. ! 6. Устройство связи по п.4, в котором преамбула имеет конфигурацию символа, так что каждый символ имеет одинаковую величину и имеет, по существу, плоскую частотную характеристику. ! 7. Устройство связи по п.1, в котором сигнал связ 1. A communication device configured for use with a communication signal having a special preamble that provides for increased bandwidth efficiency, the communication device comprising! a first device configured to manipulate a block transmission signal having a block size of N, where N is an integer greater than 1; ! wherein the block transmission signal has a preamble with a symbol configuration such that each of at least one symbol of all preamble symbols can be used for all steps of frequency offset estimation, clock synchronization, and channel estimation. ! 2. The communications apparatus of claim 1, wherein the block transmission signal has a preamble with a symbol configuration such that each of at least 50% of all preamble symbols can be used for all steps of frequency offset estimation, clock synchronization, and channel estimation. ! 3. The communications apparatus of claim 2, wherein the block transmission signal has a preamble with a symbol configuration such that each of substantially all of the preamble symbols can be used for at least two steps of frequency offset estimation, clock synchronization, and channel estimation. ! 4. The communications apparatus of claim 1, wherein the preamble is cyclically orthogonal. ! 5. The communications apparatus of claim 4, wherein the preamble uses are zero padded or cyclic prefixed. ! 6. The communications apparatus of claim 4, wherein the preamble has a symbol configuration such that each symbol has the same magnitude and has a substantially flat frequency response. ! 7. The communication device according to claim 1, wherein the communication signal
