When performing uplink asynchronous FDM signaling, power control as grouping is used. When performing uplink synchronous FDM signaling, time synchronization, frequency synchronization, and power control (such as including wireless communication device grouping) is performed.

A feedback module compares a voltage of the battery to a reference voltage to provide a charging error signal.

Abstract: A plurality of downstream channels enables communications between a CMTS and a plurality of legacy and non-legacy cable modems. A dispersion mechanism optimizes channel bonding, such that the downstream channels are interoperable with DOCSIS™-compliant, legacy cable modems. A program identifier field distinguishes between bonded and non-bonded flows. For bonded flows, a bonding group is defined to bond a set of downstream channels. The packets for each bonding group are classified into channel queues at or near a MPEG level or a packet level. To mitigate congestion and multiplexing inefficiencies, the dispersion mechanism collects real-time information to determine which channel receives the bonded packets. The dispersion mechanism includes a queue manager and a priority manager. The queue manager dynamically creates queues and allocates queue memory. The priority manager spools the appropriate bytes to an MPEG encapsulation engine for the appropriate outgoing modulator.

Abstract: Aspects of a method and system for dynamic adaptation and communicating differences in frequency-time dependent systems may include generating a time difference weighting factor and a frequency difference weighting factor, based on at least channel estimates. A time-frequency difference may be computed by forming a weighted sum comprising a time difference and a frequency difference, where forming the weighted sum uses at least the time difference weighting factor and the frequency weighting factor. A channel quality indicator (CQI) feedback message may be generated, comprising the time-frequency difference. The time difference weighting factor and/or the frequency difference weighting factor may be generated adaptively at a base station or a mobile terminal. The time difference and/or the frequency difference may be generated from estimated Signal-to-Noise-Ratios (SNRs) associated with the channel estimates. The SNRs may be based on at least the output of an MMSE receiver.

Abstract: An Inverse Transform (IT) conforming to MPEG AVC I_PCM that offers better video image quality than the MPEG-2/H.263 based video decoders and real time motion picture processing at 30 frames/seconds is described. The IT module performs 4×4 Inverse Integer transform for AVC for MPEG-2 operations on a given macro block (MB) and all its sub blocks. The IT is the third module in the data flow pipeline of a video decoder, the first two being a variable length decoder (VLD) and an inverse quantizer (IQ). The IT module gets its inputs from IQ module and feeds its processed output to a Motion compensation unit/intra-prediction (MCU-IP) module, thus reconstructing the video picture.
