#+TITLE: PROJECT: SDR Suite Lisp (Universal Literate Note)
|

|
|
|
* Overview
|
|
The *SDR Suite Lisp* project aims to develop a comprehensive Software Defined Radio environment using Common Lisp. It leverages the high-performance, threaded nature of SBCL to provide real-time signal processing across various domains, from satellite communication to passive radar and computer networking.
|
|
|
|
* Phase A: Demand (PRD)

|
|
|
** 1. Purpose
|
|
Define the functional and technical requirements for a Lisp-native SDR architecture.
|
|
|
|
** 2. User Needs
|
|
- *Real-time Signal Processing:* High-performance DSP loops in Common Lisp.
|
|
- *Multimodal Support:* Unified framework for EME, ALE, SSTV, and standard Rx (FM/AM).
|
|
- *Extensibility:* Modular "plug-and-play" architecture for new decoders and protocols.
|
|
- *Hardware Agnostic:* Support for RTL-SDR, HackRF, and high-end FPGA-based SDRs.
|
|
|
|
** 3. Success Criteria
|
|
*** TODO Core DSP Loop Benchmarking (SBCL)
|
|
*** TODO RTL-SDR Driver Interface (via CFFI)
|
|
*** TODO Basic FM Broadcast Decoder Implementation
|
|
*** TODO Spectral Waterfall Visualization Stubs
|
|
|
|
* Phase B: Blueprint (PROTOCOL)

** 1. Architectural Intent
|
|
Interfaces for IQ stream processing and protocol dispatch. Source of truth is the physical signal and the DSP mathematical specifications.
|
|
|
|
** 2. Semantic Interfaces

#+begin_src lisp

(defun sdr-perceive-stream (source-id buffer-size)
|
|
"Initializes the IQ sample stream from the hardware source.")
|
|
|
|
(defun sdr-decode-fm (iq-samples)
|
|
"Applies de-emphasis and filtering to extract audio from IQ data.")

#+end_src
|
|
|
|
* Phase D: Build (Implementation)
|
|
Current implementation status is "Architecture Research." Placeholder for CFFI bindings and DSP libraries.
|
|
|
|
* Phase E: Chaos (Verification)
|
|
Verification involves signal fidelity audits and real-time latency testing under various CPU loads.
