A modulation transmission technique comprises placing orthogonal subcarriers across an arbitrary-wide band of frequencies without a fixed pre-defined center frequency. Receivers demodulate only the sub-group of subcarriers in which they are to receive data. Thus a broadcast service with many audio programs could send signals across a wide band and receivers would only demodulate the audio channel that the user or users wanted to hear. This saves energy which is important for battery powered devices. A transform bandwidth smaller than the transform bandwidth of the transmitter is used that encompasses the receivers pass band, plus the 2 transition bands (upper and lower) of the linear filter. This technique maintains orthogonality between subcarriers. The subcarriers in the pass band are utilized and the subcarriers in the transition bands are discarded. The orthogonal subcarriers may include both orthogonal frequency division multiplexed and pulse amplitude modulated signals. A notch filter may be included in the receiver to remove unwanted non-orthogonal signals such as a television signal or other interference.

Disclosed is an apparatus and method for increasing the error correction capabilities of a receiver circuit that receives a data stream of encoded data symbols that are encoded with a linear block code. Analog and digital comparator circuits are used to detect laser clipping or analog to digital converter overloading. Corrupted symbols are detected by comparing in-phase and/or quadrature phase baseband signals with pre-determined threshold limits that indicate that the in-phase and quadrature phase signals have exceeded the normal signal trajectory of an unimpaired signal. Corrupted symbols may also be detected by determining that the laser has been clipped. Corrupted symbols are marked for erasure prior to decoding and error correction. Erasure of corrupted signals increases the error correction capabilities of the decoder circuit.

Time domain duplex (TDD) is contemplated, including controlling switches and/or amplifiers to facilitate signaling between a network and a plurality of end stations (ESs) according to a TDD control strategy. The TDD control strategy may be characterized by preventing simultaneous upstream and downstream communication between the network and one or more of the ESs over a particular frequency band. The TDD control strategy may be limited to a particular frequency range such that signaling outside of frequency range may be simultaneously communicated upstream and downstream.

A layered operating system architecture enables decoupling of a media access control (MAC) layer from a physical (PHY) layer. The decoupled MAC and PHY layer removes responsibility from the MAC layer with respect to understanding network resources, network space and network scheduling and allocation demands when processing data for transport over a network. The MAC layer may instead operate according to an allocation scheduled provided by a convergence layer responsible for understanding the varying conditions and demand attendant to supporting communications over the network.

Redistribution of network capacity in a network having a plurality of base stations is contemplated. The redistribution may include reallocating or otherwise reusing primary channels assigned to the plurality base stations to increase capacity proximate one or more of the base stations. The network capacity may be increased in this manner without having to add new base stations.

A duplex communication system having gate-implemented noise management is contemplated. The system may include a gate or other device sufficiently operable to facilitate managing upstream and downstream signaling so as to ameliorate noise funneling between communicating endpoints by selectively controlling communication paths through which noise may be propagated. Optionally, the system may be operably configured to facilitate this type of gate-implemented noise management for time domain duplex (TDD) and frequency domain duplex (FDD) communications.

A network access optimization strategy where mobile device may be directed to access particular networks depending on operation requirements and characteristic. The optimization strategy may rely on a traveling speed of the mobile to device to broadly prioritize a network type suitable for the given traveling speed.

A polling arrangement where polling frequency and/or rates may be adjusted according to activities of end stations or other elements being polled. The ability to adjust the polling activities may be used to facilitate reducing or otherwise controlling network resources allocated to the supporting the polling or other messaging depending operations.
