Multiple streams from multiple circuit paths are Block-TDM (Block-Time-Division-
Multiplexing) aggregated into a single
stream that passes via a single path through
processing circuitry capable of handling the aggregated
signal. The cost of providing redundant
processing circuitry is avoided. After
processing in the single path, the resulting
signal is Block-TDM de-aggregated to generate multiple streams. Each output
stream is substantially the same as if its corresponding input
stream had been processed in a separate path using separate processing circuitry. The path-sharing technique is
usable to pass multiple streams from multiple radio receivers through one superior
Delta-Sigma ADC (DSADC) as opposed to using multiple flat ADCs to
process information from the multiple receivers. In one example, the DSADC can be used because the aggregation is Block-TDM-based and the de-aggregator involves a digital
low pass filter. In another example, the de-aggregator involves a decoder and the aggregator involves a precoder.
