Abstract

The disclosed apparatus, structures, and methods are directed to a wireless receiver. The configurations presented herein employ a structure operative to receive a plurality of analog signals, a signal encoder configured to encode the plurality of received analog signals into a single encoded analog composite signal based on a coding scheme operating under a first code rate, a signal reconstruction module configured to segregate and reconstruct the single encoded digital composite signal into a re-encoded digital composite signal in accordance with the coding scheme operating under a second code rate. In addition, a signal decoder configured to decode the digital composite signals based on the coding scheme operating under the second code rate, and to output digital signals, in which each digital signal in the plurality of digital signals corresponds to a respective analog signal of the plurality of received analog signals.

Dependent claims

A wireless receiver, comprising:

a signal encoder configured to encode a plurality of received analog signals into a single encoded analog composite signal, in accordance with an orthogonal coding scheme operating under a first code rate;
an analog-to-digital converter configured to convert the single encoded analog composite signal into a single encoded digital composite signal containing constituent digital signals;
a signal reconstruction module configured to segregate the single encoded digital composite signal into a plurality of individual spectrum signals and reconstruct the plurality of individual spectrum signals into a single re-encoded digital composite signal in accordance with the orthogonal coding scheme operating under a second code rate, wherein the first code rate and the second code rate are not related to each other;
and
a signal decoder configured to decode the single re-encoded digital composite signal in accordance with the orthogonal coding scheme operating under the second code rate, and to output a plurality of digital signals, in which each digital signal in the plurality of digital signals corresponds to a respective analog signal of the plurality of received analog signals.
