Abstract: To reduce the number of subcarriers used for the transmission of reference symbols by base stations in an OFDM based cellular telecommunications network, the level of data for transmission from the base station to at least one subscriber station is determined and, when traffic levels are low and/or where the mobile station is unable to make efficient use of the full bandwidth, reference symbol data is transmitted from the base station using a number of the subcarriers less than the total number of subcarriers available. Thus the reference symbol frequency spread—the bandwidth between the lowest frequency subcarrier and the highest frequency subcarrier being used to transmit reference symbols—is made dependent upon the determined level of data for transmission.

To synchronize the LFSRs, a first one of the compute devices may transmit a first training block that includes a predefined bit sequence. The training block is scrambled by a transmitting (TX) LFSR on the first compute device and then transmitted to the second compute device.

The second compute device can use the outputs of the TX LFSR to determine future outputs of the TX LFSR. These future outputs are then used to initialize a receiving (RX) LFSR on the second compute device. Now, when subsequent training blocks are received, the second compute device can use the initialized RX LFSR to descramble the scrambled training blocks.

Abstract: An integrated receiver supports adaptive receive equalization. An incoming bit stream is sampled using edge and data clock signals derived from a reference clock signal. A phase detector determines whether the edge and data clock signals are in phase with the incoming data, while some clock recovery circuitry adjusts the edge and data clock signals as required to match their phases to the incoming data. The receiver employs the edge and data samples used to recover the edge and data clock signals to note the locations of zero crossings for one or more selected data patterns. The pattern or patterns may be selected from among those apt to produce the greatest timing error. Equalization settings may then be adjusted to align the zero crossings of the selected data patterns with the recovered edge clock signal.
