Abstract: Certain aspects involve power management subsystems for a distributed antenna system (“DAS”) or other telecommunication system. The power management subsystem can include a measurement module and an optimization module. The measurement module can monitor a utilization metric for a remote unit in the DAS or other telecommunication system. The power optimization module can determine whether the remote unit is underutilized based on the monitored utilization metric. The power optimization module can configure the remote unit for a low-power operation in response to determining that the remote unit is underutilized.

Abstract: One embodiment discloses an antenna structure. The antenna structure may comprise a transmit antenna element comprising a first transmit antenna sub-element and a second transmit antenna sub-element. The antenna structure can comprise a receive antenna element comprising a first receive antenna sub-element and a second receive antenna sub-element. At least one electronic component of the antenna structure may be coupled with a ground plane. The first transmit antenna sub-element, the second transmit antenna sub-element, the first receive antenna sub-element, and the second receive antenna sub-element may each comprise a first portion and a second portion. The second portion may be larger than the first portion. The first portion can be closer to a center position of an arrangement of the sub-elements than the second portion. In one embodiment, the arrangement of the sub-elements about the center position forms a four-leaf clover-like arrangement.

Abstract: A telecommunications system is provided that includes a unit for communicating channelized digital baseband signals with remotely located units. The channelized digital baseband signals include call information for wireless communication. The unit includes a channelizer section and a transport section. The channelizer section can extract, per channel, the channelized digital baseband signals using channel filters and digital down-converters. The transport section can format the channelized digital baseband signals for transport together using a transport schedule unit for packetizing and packet scheduling the channelized digital baseband signals. A signal processing subsystem can control a gain of uplink digital baseband signals, independently, that are received from the remotely located units prior to summing the uplink digital baseband signals.

Abstract: A squaring loop for a GPS receiver locks to a carrier that is bi-phase modulated with a PRN acquisition code and a data message. The receive signal is down converted and hard limited and phase measurements are made between the rising edges of a local clock and every edge of the hard limited carrier. Phase measurements made with respect to extraneous or missing transitions resulting from the data bits that would result in phase locking instability are removed by a phase evaluation comparison. Phase measurements that are outside of limits determined in accordance with the noise characteristics of the channel are excluded thereby removing measurements that would cause the instability. The phase measurements outside the limits are resonably attributable to data bit transitions rather than to noise.
