A communication system (10) receives a communication signal comprising first and second data with different compression levels, such as highly compressed and weakly compressed levels. A mode detector (15) detects the level of compression. One or more signal decoders (20, 22) decode the highly compressed data. An analyzer (30) determines the type of enhancement required. One or more processors (48, 50, 80) enhance the data as required. An encoder (60) reencodes the enhanced decoded data. Metrics (90) may aid the operation of the analyzer (30).The communication system may include telephones (120, 122, 124, 126). Processors (103, 104) enhance signals in opposite first and second directions between pairs of the telephones. A path (106) connects the processors in tandem. One or more switches (101, 102) disable signal enhancement for one of the processors depending on the compression level of the signals to avoid degrading call quality.

In order to enhance the quality of a communication signal derived from speech and noise, a filter divides the communication signal into a plurality of frequency band signals. A calculator generates a plurality of power band signals each having a power band value and corresponding to one of the frequency band signals. The power band values are based on estimating, over a time period, the power of one of the frequency band signals. The time period is different for different ones of the frequency band signals. The power band values are used to calculate weighting factors which are used to alter the frequency band signals that are combined to generate an improved communication signal.

Hybrid intra-cell / inter-cell remote unit antenna bonding in multiple-input, multiple-output (MIMO) distributed antenna systems (DASs), and related components, systems, and methods. The MIMO DASs are capable of supporting distributed MIMO communications with client devices. To provide enhanced MIMO coverage areas, hybrid intra-cell / inter-cell remote unit antenna bonding is employed. For example, if a client device has acceptable MIMO communications signal quality with MIMO antennas within a single remote unit, intra-cell bonding of the MIMO antennas can be employed to provide MIMO coverage for MIMO communications, which may avoid power imbalance issues that would result with inter-cell bonded MIMO antennas. However, if a client device has acceptable MIMO communications signal quality with MIMO antennas in a separate, neighboring remote unit(s), inter-cell bonding of the MIMO antennas can be employed to provide MIMO coverage for MIMO communications.
